ETI PI-2500 Mobile Circuit Breaker Tester

Input: 208-240 / 480 VAC +/- 10% Switch Selectable

• 15 KVA Continuous (Test up to 2000 Amp Circuit Breakers)
• Digital Memory Ammeter Controller MAC-21
• Rugged enclosure with pneumatic wheels for ease mobility

The PI-2500 is a versatile and technologically advanced primary injection test set capable of testing circuit breakers up to 2000 amperes frame size. It incorporates an improved low impedance output transformer with dual secondaries to provide optimal impedance matching to a wide range of breaker sizes. High capacity internal fan cooling allows maximum utilization of the output transformer and faster recovery after overload conditions. It is housed in a rugged aluminum frame enclosure with removable sides allowing easy access to all internal components to facilitate ease of service and maintenance. The sides are clear of protruding components, as well as locking pneumatic swivel castors on one end provide ease of mobility, and allow the test set to be moved on rough surfaces. A flat area on the top surface can be used for convenient placement of manuals, breaker curve books, and auxiliary instruments.

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-2500 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. The reduced length and width of the test set allows it to be maneuvered in tight spaces and it can be lowered into a shaft 26” x 30”, or a manhole 40” diameter. Provisions have been made on the bottom of the frame for a lifting sling to be attached without slipping from the corners. The rugged silver plated copper stab adaptors supplied with the test set are designed to be used for both vertical and horizontal stabs, and have both ½” and ¾” output plates.
