The Vacuum Interrupters CBT-1202 Circuit Breaker Timer is a self-contained, multi-use test set designed to operate and interact with all types of circuit breakers. Incorporating a digital timer to capture and store trip, close and bounce times, it is a handy, field portable unit that also incorporates a power supply for charging spring charged breakers while outside their cubicle, switching to trip and close the breaker, and has unique cable sets which speed and simplify connection to the breaker under test.

The power supply incorporated in the CBT-1202 provides a 0-120VAC and 0-125VDC output for charging spring charged circuit breakers while outside their cubicle. Provisions are also provided to accept and distribute variable voltages from an external power supply.

The charging power supply and breaker trip/open and close switching are frequently used when working on a breaker even when the timer function is not required.

The built-in timer records breaker opening, closing and trip times; and 10 test results can be stored in the internal memory.

Unique, pre-wired 15-foot cable assemblies provide simple, fast connection to the circuit breaker under test. In addition to a universal cable set, breaker specific cable sets are available for GE PowerVac (Vacuum Interrupters CBT GE PowerVac Breaker) and Eaton/Westinghouse/Cutler-Hammer VCP-W. Other pre-wired cable sets are available for all types of circuit breakers.

Compact and lightweight, the Vacuum Interrupters CBT-1202 Circuit Breaker Timer is ideally suited for both field and shop use.
