4 WL Circuit Breaker Selection and Application Guide

Businesses are becoming increasingly more intelligent about the way they consume energy. Industrial and Commercial energy consumers are continuously looking for practical and efficient methods of measuring their energy usage while simultaneously ensuring any possible downtime is minimized. At Siemens we understand those needs and we have developed products and solutions to help energy consumers achieve their goals.

One of our solutions begins with our world-class WL Circuit Breakers. The WL line-up of breakers developed by Siemens combines decades of patented circuit breaker protection experience with the latest technology in circuit breaker performance and communication.

A good example of our innovative technology is, Dynamic Arc-Flash Sentry® (DAS). DAS is a solution that allows users the ability to automatically lower the down-stream available fault current when facility personnel are nearby the electrical equipment. Helping our customers provide a safer work-place environment is an important part to our overall solutions.

Other valuable aspects that complement our solutions are the WL circuit breaker’s ability to gather energy and environmental data and send it to a central or remote monitoring network system. You’ll find these capabilities and more when you take a closer look at WL circuit breakers features within this guide.

WL Circuit Breaker features and benefits

• 3 frame sizes: Three frame sizes that cover a wide range of continuous current ratings allow for flexible exchange of breakers to other compartments and reducing the footprint of the breaker enclosures.

• Ready-to-close indication: Built-in check points of the breakers mechanical operator provide an additional layer of safety and external controls by inhibiting the breaker from closing until certain conditions are satisfied.

• 100% rating: All model breakers are designed for continuous operation at their maximum current ratings without de-rating the frame.

• High-efficiency: Low loss of energy flowing through the breaker reduces the operating costs.

• Bi-directional feed: Top or bottom supply feed without any hardware configuration changes.

• Rogowski coil sensing: Full range sensing without tap terminals or exchanging sensors to match load change requirements.

• Modular trip unit: Upgrading to a higher or lower current rating, adding ground fault, power monitoring or communication is cost effective and expandable using separately available modules.

• Common accessories: Interchangeable accessories for all frame sizes makes upgrading easy and readily available.

Practical solution

Applications The WL line of power breakers are protecting electrical distribution applications like waste water treatment, industrial plants, hospitals, transportation systems and data centers just to name a few. Yes, mission critical applications trust the Siemens WL circuit breakers to operate safe and reliably. The compact modular design provides higher power density in a section or line-up of distribution gear. Components like spring-charging motor, shunt trips, and trip units are common across the entire line of breakers. That allows users the ability to stock fewer spare parts or exchange options if necessary. Common options and accessories also make learning how to order, maintain and operate the WL much easier than most breakers on the market today.

WL circuit breakers are manufactured and performance tested to comply with UL489 and UL1066 standards for listed products.

UL/CSA 489 Listed type WL low voltage insulated case circuit breakers are generally intended to provide service entrance, feeder, and branch circuit protection in accordance with UL/CSA 489 Standard for Safety for Molded-Case Circuit Breakers, Molded-Case Switches, and Circuit-Breaker Enclosures. This versatile family of insulated case circuit breakers is acceptable for use within low-voltage switchboards (i.e. UL 891), low-voltage motor control centers (i.e. UL 845), and other types of industrial control equipment (i.e. UL 508 series). Certain options and maintenance capability may be limited in comparison to the UL1066 Listed circuit breakers.

UL file numbers E231263, E236091 and E236299 apply.

UL 1066 Listed type WL low voltage power circuit breakers are generally intended to provide main and feeder circuit protection in accordance with UL1066 Standard for Safety for Low-Voltage AC and DC Power Circuit Breakers Used in Enclosures. Presently, there is not an equivalent CSA standard to UL 1066, and therefore these circuit breakers do not carry a CSA listing mark. These circuit breakers are constructed in compliance with ANSI/IEEE C37.13, and performance tested in accordance with ANSI C37.50. Throughout this document any reference to UL1066 will also mean ANSI C37 Certified. This versatile family of power circuit breakers is acceptable for use within low voltage switchgear (i.e. ANSI/IEEE C37.20.1, ANSI/IEEE C37.20.7, and UL 1558), low voltage switchboards (i.e.

UL 891), low voltage motor control centers (i.e. UL 845), and other types of industrial control equipment (i.e. UL 508 series). Certain options and ratings may be limited may be limited in comparison to the UL/CSA 489 Listed circuit breakers. UL file numbers E240124, E240232, E240233 and E236299 apply.

Electronic Trip Unit (ETU)

Electronic trip units (ETUs) Power system protection is necessary to treat common types of abnormal occurrences, such as overloads or faults that can lead to electrical power system failure.

The methods for detecting and clearing such abnormalities and restore to normal operation is an engineered technique.

Adequate protection requires constant measurements of certain system quantities, such as voltages and currents, comparing those system quantities, or some combination of the quantities, to a threshold setting computed by a systems engineer and set into an electronic trip unit like those available on the WL breakers. It’s equally important for power system protection to perform under normal operating conditions. If the above thresholds are set too low the power may be interrupted unnecessarily causing loss of productivity or safety provisions.

The WL circuit breaker offers a practical means of setting power system protection through vast selectivity available in its Electronic Trip Unit (ETU). WL ETUs have a wide range of protective settings for implementing simple or complex coordination schemes and configuring reliable system protection.

ETU enhanced features

• Extended Instantaneous Protection (EIP): Allows the entire range of WL ampacities to be applied at the withstand rating of the breaker with minus 0% tolerance; that means no instantaneous override whatsoever. EIP further enables the circuit breaker to be applied up to the full interrupting rating of the breaker on systems where the available fault current exceeds the withstand rating, even with LS-only trip units.

• Dynamic Arc-Flash Sentry (DAS): Allows you the ability to execute a faster coordinated trip condition should an arc fault event occur while personnel are within the arc flash boundary. When the presence of personnel is no longer in the arc flash boundary, DAS will default back to maintaining your selective trip coordination through time delay functions.

This is like toggling between two trip units on one breaker.

DAS can be activated by a simple contact closer, so a wide range of activation devices can be used to enable DAS.

• Selectable I4t: ETU745 and 776 make it possible to switch over from an I2t to an I4t inverse-time function for overload protection. This selectivity increases optimization of coordinated overload protection when overload fuse protection is also provided.

ETU basic functions Long-time trip The long-time delay adjustment is used to set the tripping delay of the circuit breaker based on the magnitude of the overcurrent condition (6 times lr). For example if the rating plug is 2000 amps and the long-time delay is set to 10 seconds, a fault current of 12,000 amps (6 x 2000) will cause the breaker to trip after 10 seconds. Long-time is an inverse of I2t ramp function. This means the higher the current, the shorter the time the circuit breaker will remain closed. An Alarm LED indicator will flash during the delay period and a separate “Trip L” indicator may turn on if the breaker trips on long-time function.

Short-time trip The short-time pickup adjustment is used to set the level of high current the breaker will carry for a short period of time without tripping. This adjustment is set in multiples of the value of the rating plug (Ir). Together with the short-time delay, this adjustment allows downstream breakers time to clear short circuit faults without tripping upstream breakers. Short-time delay is used to set the time interval the breaker will wait before responding to the current value selected by short-time pickup.

There are two modes of operation: fixed and I2t. The I2t delay has the characteristic of being inversely proportional to the square of the magnitude of the current. This means higher overcurrent conditions have shorter delays. An Alarm LED indicator may flash during the delay period and a separate “Trip S” indicator will turn on if the breaker trips on short-time function.

Instantaneous trip The instantaneous pickup adjustment is used to set the current level at which the breaker will trip without an intentional time delay. Non-delayed tripping as a result of severe over-current minimizes potential damage to the electrical system and equipment.

Ground fault The ground fault pickup adjustment is used to set the level of ground current at which circuit interruption will be initiated.

Together with ground fault delay, this adjustment allows selective tripping between main and feeder or downstream breakers.

The ground fault delay adjustment is used to set the time interval (in seconds) the breaker will wait before responding once the ground fault pickup level has been reached. The available ground fault delay settings available are: inverse time (I2t) or fixed delay.

ETU communication The ETU uses a Siemens proprietary communication network called CubicleBus. The CubicleBus network ensures all Siemens devices are able to transmit data reliably and efficiently. The ETU can not be connected directly any other network so the use of converters are necessary to allow communication between the ETU and the outside world. The WL has three types of converters to allow communication between the ETU and computer type equipment. The three converts are:

• PROFIBUS (COM15)

• ModBus (COM16)

• HTML or TCP/IP (BDA)

The WL PROFIBUS converter is model ‘COM15.’ The COM15 device acts as an interface between the WL breaker and the information environment. A joint device master file (GSD) can be used for integrating WL circuit breakers in a PROFIBUS-DP network. The advantage of this joint communication profile is that the same software can be used for automation, monitoring and control systems.

The WL ModBus converter is model ‘COM16’. The COM16 device enables the WL breaker to be connected to any Modbus master network. Universal Modbus mapping can be used to allow custom monitoring and controls with a centralized monitoring system.

The Modbus port is configured for RS485 connectivity and can easily be daisy-chained to several WL breakers to create a serial-network suitable for connecting to a LAN or WAN network.

The WL HTML or TCP/IP converter is called ‘BDA.’ The BDA is a microcomputer with an embedded Linux operating system running a web server application. The HTML pages and JAVA codes are stored internal to the BDA and can be accessed with an external PC web browser. All of the viewable web pages are stored in the BDA. The BDA communicates to the ETU through a front connected ribbon-cable. The PC accesses the BDA through an integral DB-9 serial port or an RJ45 Ethernet port.

All three converters require a 24VDC Class 2 power supply.

See External Accessories for more information on available power supplies.

Electronic Trip Unit (ETU)

Power metering function In addition to excellent protection capabilities, the WL ETU has unparalleled power metering functionality. True RMS current sensing for metering is obtained from the same current sensors used for overload protection. ETU power metering can measure the following:

Potential transformers (PTs) are required to step down the supply voltage to a level that is suitable for local input connection to the breaker. PTs must be wired to the secondary connections of the breaker and configured for three-phase, three-wire or three-phase, four-wire supply system. The measured values can be sent to a central database for future power analysis or consumption reports.

Metering is not field installable – it must be configured in the initial breaker purchase.
