Current testing device CB-360-DC

electricmanualcircuit breaker

• Capable of testing electromechanical or thermal-magnetic trip devices with a DC current • Digital timer • High current output up to 30 000 amperes The CB-360-DC DC circuit breaker tester is a mobile, high current test set designed specifically for testing DC circuit breakers. It incorporates a variable high current DC output, control circuitry, instrumentation, and overload and short-circuit protection. It has been designed to test low voltage DC circuit breakers with a 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.
