The PI-800 Circuit Breaker Test System incorporates modular design and flexibility to provide unequaled capability in a portable package. The PI800 used alone, on 120 or 240 VAC supplies, generates continuous current of 400, 800, amps at 4.2 kVA, with peak output to over 10x. The units are housed in rugged interlocking suitcase-size enclosures. Each piece weighs no more than 125 pounds, allowing one person hand truck mobility. Basic operation is very simple, and the proven MAC-21 instrumentation provides optimal output control and measurement.
The PI-800 is a versatile and technologically advanced primary injection test set capable of testing circuit breakers up to 800 amperes frame size. It incorporates a special lightweight toroidal output transformer with dual primaries to facilitate its use on power sources of 120 VAC as well as 240 VAC, and quad secondaries to provide optimal impedance matching to a wide range of breaker sizes. Internal fan cooling allows maximum utilization of the output transformer and faster recovery after overload conditions.
Applications
This test set will test low-voltage, molded-case and metal-clad, direct acting AC circuit breaker from various manufactures. The test set can also be used on high current applications like ratio transformers, and heat runs.
Using SCR’s the PI-800 eliminates closing time errors. Initiation at the zero crossover point eliminates DC offset in the current waveform and results in accurate, repeatable test results even with short-duration currents for high speed solid state or electromechanical trip devices.
