Incorporating the latest technological advancements, the Megger DDA-6000 Universal Circuit Breaker Test Set is designed specifically to test low-voltage power and molded-case circuit breakers equipped with thermal, magnetic or solidstate trip devices. The unit is fully compliant with NEMA AB-4 test guidelines.

Tests are performed by simulating an overload or fault condition. The test set is an integrated test system that provides a variable, high-current output, and incorporate all control circuitry and instrumentation necessary to test direct-acting circuit breakers accurately, efficiently and safely.

The unique transformer and circuit design results in a very high-capacity test set in a very compact size. Advanced digital control and instrumentation provides exact testing capacity.
