The Electrical Test Instruments PI-6000 tests low-voltage, molded-case and metal-clad, direct acting AC circuit breakers. The test set can also be used on high current applications like ratio transformers, and heat runs.
The ETI PI-6000 is a versatile and technologically advanced primary injection test set capable of testing circuit breakers up to 6000 amperes frame size. It incorporates an output transformer with dual primaries to facilitate its use on power sources of 480 VAC as well as 240 and 208 VAC, and dual secondaries to provide optimal impedance matching to a wide range of breaker sizes. An internal voltage sensor automatically configures the AC control power section to be energized only when properly configured for the applied voltage.
The ETI PI-6000 features dual temperature protection one for the output bus, and the other for the vernier Powersatat™. If either temperature exceeds a safe operating level, the interlock is asserted and the output section is de-energized. Primary catastrophic overload protection for the test set is accomplished with input fuses having high interrupting current capacity.
