The Megger CB-360-DC and CB-120-DC DC Circuit Breaker Test Sets are mobile, high-current test sets designed specifically for testing dc circuit breakers. They incorporate a variable high-current dc output, control circuitry, instrumentation, and overload and short-circuit protection.
Applications
The Megger CB-360-DC and CB-120-DC DC Circuit Breaker Test Sets is designed to test low-voltage dc circuit breakers with dc current. The unit provides the capability of calibrating and functionally testing the time-delay characteristics of the electromechanical or thermal-magnetic trip devices on dc circuit breakers. This is accomplished by simulating an overload or fault condition on the circuit breaker.
