Megger DDA-3000 Universal Circuit Breaker Test Set:
– New DDA-1 Digital Data Acquisition
– High-current output: 35,000 A
– Variable pulse time and firing angle output current control
– Complies with NEMA AB-4 Test Guidelines
The DDA-3000 is designed specifically to test low-voltage power and molded-case circuit breakers equipped with thermal, magnetic or solid-state trip devices. 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. The DDA-3000 can also be used for other high current applications, such as verifying the ratio of current transformers and performing heat runs or primary injection testing of high-voltage breakers and their associated protective relays.
