The PI-800 Gen2 Circuit Breaker Test System incorporates modular design and flexibility to provide unequaled capability in a portable package. The PI-800 Gen2 generates continuous current of 800 amps at 4.2 kVA, with peak output to over 10x on 240 VAC supplies. It comes in two switch-selectable input voltage options: Option A at 120 – 240 VAC, and Option B at 208 – 277 VAC. The units are housed in rugged interlocking suitcase-sized enclosures.

The units are housed in rugged interlocking suitcase sized 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 Gen2 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.
The PI-800 Gen2 consists of a strong aluminum frame, housed in a rugged plastic and aluminum enclosure with removable sealed front and back lids. 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 with a variety of connectors for 120 VAC, 208 VAC, 240, or 277 VAC (depending on the model option selected). Individual leads may also be used to connect to bus work The output connections are on the rear, along with an auxiliary Output ON indicator, configuration switch, and air output from the fans, which can help cool cables and breakers. Comfortable recessed side handles provide ease of mobility.
The MAC-21 instrumentation is supplied in a separate rugged portable case, interlocks on top of the PI-800, and connects to a cable in the rear of the test set.
The eight silver plated output bus connectors allow configuration for continuous outputs of 800 amperes at 4.2 VAC, and 400 amperes at 8.4 VAC, for testing molded case breakers with cables. They can also be connected for 1600 amperes at 2.1 VAC, which can be used for CT testing, heat runs of bus connections and limited testing of air draw-out breakers. They have pressed-in 3/8″-16 stainless steel threaded inserts, which eliminates the need for nuts, and the configuration bars are slotted for quick and easy changing for various breaker sizes.
This test set will test low-voltage, molded-case and metal-clad, direct acting AC circuit breakers 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 Gen2 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 electro-mechanical trip devices.
Serial port: This standard serial port may be connected to a printer, computer, or other device to print or store time and current values of test results in ASCII format. It is set for 9600 baud, 8 bits, 1 stop bit, no parity. This interface enables you to download data into various computer software programs.
Initiating Control: The advance initiate circuitry provides both pulse preset modes for cycles or seconds for output duration. The pulse mode automatically pulses the output to any preset programmed duration. This provides additional testing capabilities for electro-mechanical and solid state trip devices. A short preset pulse duration also allows for instantaneous tripping without preheating the breaker under test. A long preset time can used for heat runs on cables or other devices up to maximum 9999 seconds.
Zero DC Offset: Use of digitally controlled SCR’s instead of a contactor to initiate the output of the test set eliminates closing time error and thereby ensures precise initiation at the zero crossover point of the output current waveform every time. Initiation at the zero crossover point ensures symmetrical output current by eliminating DC offset in the current waveform. Therefore accurate, repeatable test results are assured even with currents of very short duration, as when conducting tests of instantaneous or short delay trips.
