The PI-1600 Circuit Breaker Test System incorporates modular design and flexibility to provide unequaled capability in a portable package. The PI1600 test set is two test sets in one. The PI-800 section can be 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. When configured for the PI-1600 the PI-AUX output unit is connected in series or parallel to the PI800. The PI-AUX boosts total power to 9.8KVA, and allows testing of drawout breakers and MCB’s to 1600 Amps. 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 MAC-21 instrumentation is supplied in a separate rugged portable case, interlocks on top of the PI800, and connects to a cable in the rear of the test set.
The PI-1600 consists of a strong aluminum frame, housed in a rugged plastic and aluminum enclosure with removable sealed front and back lids. Comfortable recessed side handles provide ease of handling and mobility. All controls, indicators, and input connections are on the front panel. The versatile 50 amp input plugs may be connected to heavy duty portable cords for 120 VAC, 208 VAC, or 240 VAC. Individual leads may also be used to connect to buswork.
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-1600 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.
