CBT-1201 Circuit Breaker Timer

This 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/open, close and bounce times, it can store 10 test results in its internal memory.

It is a handy, field portable unit that also incorporates a fixed power supply (120Vac/120Vdc) for charging spring charged breakers while outside their cubicle and switching to trip and close the breaker. Also included are provisions to accept and distribute other voltages from an external variable power supply.

Included is a unique, pre-wired, universal 12 foot cable assembly which provides simple, fast connection to the circuit breaker under test. In addition to a universal cable set, the CBT-1201 can be provided with breaker specific cable sets for GE PowerVac, Eaton/Westinghouse/Cutler-Hammer VCP-W, and other types of circuit breakers.

The CBT-1202 has the same capabilites as the CBT-1201 described above except the power supply incorporated in the CBT-1202 provides a variable 120Vac/125Vdc output for charging spring charged circuit breakers while outside their cubicle AND in addition to the universal cable set, it can be provided with breaker-specific plugs to further simplify connection to the breaker.

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

Compact, light-weight, and rugged, the CBT-1201 and CBT-1202 circuit breaker timers are ideally suited for both field and shop use.
