Cummins provides complete backup power systems for hospitals, data centers and other critical facilities

BTPC Transfer Switch

The BTPC closed–transition bypass switch completes Cummins Power Generation’s line of backup power system components designed to work together for optimum performance.

MINNEAPOLIS — Cummins Power Generation now offers closed–transition bypass switches from 150 to 4,000 amps for critical locations such as hospitals, data centers and 24/7 call centers. Cummins’ BTPC bypass switches offer redundant power transfer capability for situations where even a brief power interruption can have serious consequences. The closed–transition BTPC switch automatically transfers loads between two live sources (utility and backup) without interruption.

Cummins is the industry’s only single–source supplier of auxiliary power systems. Karl Westenfield, director, ATS business, noted that no other company designs and manufactures the full range of components — including generators, paralleling switchgear and transfer switches — that enable the customer to obtain a complete system from a single source. “We offer our customers a level of compatibility, responsibility and accountability that our competition cannot match, ” Westenfield said. “This integration of power generation, control and switching equipment is particularly important in closed–transition applications. For example, our closed–transition transfer switches include active synchronizing capability that makes closed–transition operation more reliable without adding cost and complexity to the system.”

The BTPC consists of a rail–mounted, removable automatic transfer switch (ATS) and a fixed, manually operated bypass switch. Before the ATS is pulled out for repair or maintenance, the load power is diverted to the bypass switch. By having the bypass switch activated before the ATS is disconnected, the power supply continues without interruption. After the bypass switch is engaged, the ATS can be placed in one of three positions: connected (normal), test (powered but offline) and isolated (disconnected).

If utility power falters while the ATS switch is offline or disconnected, the bypass switch activates the backup generator and allows manual transfer between utility and backup power.

BTPC switches from Cummins Power Generation are UL listed, having passed the tests required by UL 1008, the strict standard for emergency, legally required and standby applications. Safety features include closed–door ATS isolation to protect against arc flash, and shutters to protect the stationary bypass terminals during removal.

BTPC switches use field–configurable PowerCommand® microprocessor–based controllers featuring easy–to–use push–button controls for activating testing, programming timing delays and setting the exercise clock. Flash memory retains settings, even if the switch loses power. LED indicators provide at–a–glance system status, and a digital display provides status information on other ATS equipment in the facility. In a fully integrated Cummins system, the ATS controller also displays generator set status information.
