CIRCUIT BREAKER TEST SETS WITH 1,000-5,000 AMP OUTPUT:

• Ideal for testing thermal, magnetic, and solid-state motor overload relays, as well as molded-case circuit breakers and ground fault trip devices
• They can also be used in many other applications requiring a high current source Designed using proven technology, these units combine a variable high current output with user-friendly controls and precision instrumentation

CIRCUIT BREAKER TEST SETS WITH 8,000-75,000 AMP OUTPUT:

• Test virtually any low voltage, molded case, or metal clad direct acting AC circuit breaker by simulating overload and fault conditions
• Test current transformers and thermal or magnetic motor overload relays
• Configured in a series, can be used for substation maintenance, primary injection testing on high voltage circuit breakers and protective relays

• Fully automated testing
• Precise, repeatable current pulses with minimal distortion
• Current wave form display

MICROHMMETER-CONTRACT RESISTANCE METERS:

The MRM Series will accurately measure very low contact resistances on all types of electrical products including motors, switchgear, breakers, busbars, generators, reclosers, transformers.

• 4-wire Kelvin measurement
• Easy to read digital screen display
• Printable test results via external or built-in printer
• IEC safety compliant

AC VACUUM INTERRUPTER TEST SETS:

Designed primarily for vacuum interrupter testing; however, these units can be used for testing breakers, switchgear and many other electrical apparatus.
