MasterPact™ Circuit Breakers

Introduction

800–1600 A MasterPact NT Drawout Circuit Breaker

MasterPact™ NT/NW Universal Power Circuit Breakers are designed to protect electrical systems from damage caused by overloads, short circuits and equipment ground faults. All MasterPact circuit breakers are designed to open and close a circuit manually, and to open the circuit automatically at a predetermined overcurrent setting. MasterPact circuit breakers can also:

• Enhance coordination by their adjustability.

• Provide integral ground-fault protection for equipment.

• Provide high interrupting ratings and withstand ratings.

• Provide communications.

• Provide power monitoring.

• Provide protective relaying functions.

• Provide zone-selective interlocking (ZSI) which can reduce damage in the event of a fault.

Class 0613 MasterPact™ Circuit Breakers

The 800–2000 A ANSI Low Voltage Power Circuit Breakers type L1F and Insulated Case Circuit Breaker type LF are tested to show the arc flash hazard risk category as referenced by NFPA® 70E.

Circuit breakers should be applied according to guidelines detailed in the National Electrical Code® (NEC®) and other local wiring codes.

MasterPact circuit breakers are available in Square D™ or Schneider Electric™ brands.

UL File Numbers:

• MasterPact NW: E161835 Vol. 2 Sec. 1

• MasterPact NT: E161835 Vol. 2 Sec. 2

Features and Benefits High Ampere Interrupting Rating (AIR): ANSI Certified MasterPact NW circuit breakers have an interrupting rating of 200,000 A at 508 Vac without fuses.

High Short-Time Current Rating: MasterPact NW circuit breakers have exceptional short-time ratings—up to 100,000 A.

100% Rated Circuit Breaker: MasterPact circuit breakers are designed for continuous operation at 100% of their current rating.

Reverse Fed Circuit Breaker: MasterPact circuit breakers can be fed either from the top of the circuit breaker or from the bottom.

Two-Step Stored Energy Mechanism: MasterPact circuit breakers are operated via a stored-energy mechanism which can be charged manually or by a motor.

The closing time is less than five cycles. Closing and opening operations can be initiated by remote control or by push buttons on the circuit breaker front cover. An O–C–O cycle is possible without recharging.

Drawout or Fixed Mount, 3-Pole (3P) or 4-Pole (4P) Construction: ANSI Rated, UL Listed and IEC Rated MasterPact circuit breakers are available in drawout or fixed mounts, with either three-pole or four-pole construction.

Field-Installable Trip Units, Sensor Plugs and Accessories: Trip units, sensor plugs and most accessories are field installable with only the aid of a screwdriver and without adjusting the circuit breaker. The uniform design of the circuit breaker line allows most accessories to be common for the whole line.

Reinforced Insulation: Two insulation barriers separate the circuit breaker front from the current path.

Isolation Function by Positive Indication of Contact Status: The mechanical indicator is truly representative of the status of all the main contacts.

Segregated Compartment: Once the accessory cover has been removed to provide access to the accessory compartment, the main contacts remain fully isolated. Furthermore, interphase partitioning allows full insulation between each pole even if the accessory cover has been removed.

Front Connection of Secondary Circuits: All accessory terminals (ring terminals are available as an option) are located on a connecting block which is accessible from the front in the connected, test and disconnected positions. This is particularly useful for field inspection and modification.

Anti-Pumping Feature: All MasterPact NTand NW circuit breakers are designed with an anti-pumping feature that causes an opening order to always takes priority over a closing order. Specifically, if opening and closing orders occur simultaneously, the charged mechanism discharges without any movement of the main contacts keeping the circuit breaker in the open (OFF) position.

In the event that opening and closing orders are simultaneously maintained, the standard mechanism provides an anti-pumping function which continues to keep the main contacts in the open position.

10 0613CT0001

In addition, after fault tripping or opening the circuit breaker intentionally (using the manual or electrical controls and with the closing coil continuously energized) the circuit breaker cannot be closed until the power supply to the closing coil is discontinued and then reactivated.

NOTE:When the automatic reset after fault trip (RAR) option is installed, the automatic control system must take into account the information supplied by the circuit breaker before issuing a new closing order or before blocking the circuit breaker in the open position. The information is on the type of fault, e.g.

overload, short-circuit or ground fault.

Disconnection Through the Front Door: The racking handle and racking mechanism are accessible through the front door cutout. Disconnecting the circuit breaker is possible without opening the door and exposing live parts.

Maintenance: To maintain MasterPact's operating and safety characteristics from the beginning to the end of its service life, Schneider Electric recommends that systematic checks and periodic on-site maintenance be carried out by qualified personnel, as indicated in bulletin 0613IB1202, "Maintenance and Field Testing Guide for MasterPact NTand NW Circuit Breakers".

0613CT0001 11

Schneider Electric Field Services offers a wide portfolio of field maintenance services named ONSITE MAINTENANCE which offers four types of services:

• OnSite Repair, which repairs a system in view of fulfilling a required function

• OnSite Preventive Maintenance, which carries out, at predetermined intervals, checks intended to reduce the probability of a failure or deterioration in the operation of a system

• Onsite Condition Maintenance, based on the recording and analysis of system parameters in addition to preventive checks, detects drift from the initial state and/or significant trends in performance. Using OnSite Condition Maintenance makes it possible to anticipate any necessary corrective action required to ensure equipment safety and continuity of service, and make repairs immediately if spare parts are onsite, or to plan the repair for a more convenient time.

• On-Site Asset Diagnostic, which is used to identify symptoms of malfunction or degradation before problems occur, things not possible to detect during standard preventive maintenance. It detects functional deviations versus original (new device) specifications. A repair plan is recommended to recover the original conditions when deviations are diagnosed.

The Maintenance Guide is available on the Internet (www.se.com) and provides detailed information on:

• types of maintenance required, depending on the criticality of the protected circuit, risks involved if the component ceases to operate correctly,

• what is understood by the terms normal, improved and severe environment and operating conditions,

• periodic preventive maintenance operations that should be carried out under normal environment and operating conditions as well as the level of competence required for the operations,

• the environment and operating conditions that accelerate device aging,

• the recommended timing of on-site maintenance according to equipment criticality and the environmental conditions in which the equipment operates.

Arc Chamber An example of preventive maintenance: the arc chambers are removed to allow visual inspection of the contacts and wear indicator groove (see Contact Wear Indicators, page 12 for how wear is indicated). The operation counter can also indicate when inspections and possible maintenance should be done. The life of the circuit breaker may be extended by replacing the arc chamber and/or spring-charging motor of ANSI Certified circuit breakers. See bulletin 0613IB1202, available at www.se.com, for information on normal and adverse operating conditions.

MasterPact NW with ArcBlock™ Technology The MasterPact NW low-voltage power circuit breaker and insulated case circuit breaker are available with ArcBlok technology designed to mount in an ArcBlok drawout cradle.

The MasterPact NW with ArcBlok technology interfaces with the ArcBlok cradle to prevent arcing events by enclosing the phases at the primary connection of the cradle. If for any reason an arcing event happens, with the separation between phase to phase and phase to ground, the arc is extinguished in less than 12 ms to reduce arc flash energy.

The MasterPact NW with ArcBlok technology is tested as part of Arc Resistant Equipment to ANSI C37.20.7.
