THE TRANSFER OF POWER

IS ALWAYS CRITICAL IN ANY

APPLICATION

Introducing the new breed of smarter, tougher and faster transfer switches to meet the need for flawless power transfer for mission-critical applications as well as commercial, light commercial and light industrial users in addition to small businesses and residential users.

From dense urban areas to remote locations, and from home and small businesses to industrial solutions, we’re engineering the next generation of reliable power.

PowerCommand® transfer switches are your direct connection to reliability, connectivity and real-time data about power system performance. Advanced microprocessor control technology ensures easy yet reliable operation. And a robust, high contact-force mechanism withstands thousands of cycles in utility-to-generator, utility-to-utility or generator-to-generator installations.

Transfer switches are listed to UL 1008: Standard for Safety – Transfer Switch Equipment. UL 1008 testing requires enduring high overload and fault currents for up to thousands of switching cycles and tens of thousands of short circuits to ensure the highest levels of safety, reliability and longevity.

MISSION-CRITICAL, INDUSTRIAL

AND ENHANCED COMMERCIAL

APPLICATIONS

POWERCOMMAND® X-SERIES

X-Series transfer switches are designed specifically for mission-critical, industrial and enhanced commercial applications in which reliable power is paramount to the safety and vitality of our communities.

X-Series transfer switches are available as automatic (open/closed transition) and non-automatic, with service or non-service entrance.

The blow-on technology utilized by the high-endurance mechanism (HEM) uses that same electromagnetic energy to hold the contacts closed during a fault, practically eliminating arcing, contact damage and performance degradation. The HEM is designed to enable the X-Series to carry up to 100% of its rated load.

(6317704(US)-Cummins-TransferSwitch_v9.indd 4(6317704(US)-Cummins-TransferSwitch_v9.indd 4 3/10/22 3:40 PM3/10/22 3:40 PM

BTPC bypass isolation transfer switches combine a draw-out ATS with an isolation mechanism and a manual bypass switch to provide redundant power transfer and re-transfer capabilities for mission-critical applications.

BTPC switches are available with closed transition for transferring loads without interruption. Like conventional transfer switches, BTPC transfer switches are designed for operation and switching of electrical loads between primary power and standby generators.

The switch monitors both power sources, signals generator startup, automatically transfers power, and returns the load to the primary power source when the utility returns and stabilizes.

Amps

� 150A to 4,000A

Bypass Isolation

� Combines a draw-out automatic transfer switch with isolation mechanism and a manual bypass switch

� Provides redundant power transfer and re-transfer capability for critical need applications requiring a reliable power supply to the load

Bypass

� Bypass switch and transfer switch have identical electrical ratings

� Bypass contacts carry current only during bypass operation

Mechanical Flags and Transfer Switch

� Indicate bypass and transfer switch position

Easy Operation

� Bypass and isolation functions are simple, requiring only two operating handles

Draw-out positions

� Connected, tested and isolated with door closed for safety

Heavy-duty, Three-point Latches

� Ensures door will stay closed without the need for screw-in fasteners

Positive Interlocking

� Mechanical and electrical interlocking prevent source-to-source connection through the power or control wiring
