Digital Circuit Breaker Analyzer CBT-3500
The CBT-3500 is Amperis’ second generation, stand-alone, digital, microprocessor controlled, circuit-breaker timer.
It measures the elapsed time from the instant a breaker coil is energized to the instant of opening or closing of a circuit-breaker’s dry contacts. In addition to timing a breaker’s contact response time, the CBT-3500 can also time relays or other switching functions that use an initiating trigger voltage (30 - 300 Volts DC or AC).
The timer-triggering voltage starts three independent electronic timers. Each timer is individually stopped by its respective dry-contact closing or opening. The CBT-3500 can fully analyze the timing of all circuit breaker operations (Open, Close, Open – Close, and Close – Open). Timing results are displayed in milli-seconds and cycles on the unit’s back-lit LCD screen and can be printed on the built-in 2.5 inch wide thermal printer.
