These High Current Test Sets are built for field or shop use. Designed using the latest technology; these units combine a variable high current output with the appropriate controls and instrumentation. The test set is 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.

The HC2 is capable of a 2000 amp instantaneous output. Sufficient current is available for testing the time delay characteristics of motor overload relays and molded case circuit breakers.

The unique auto-sensing feature makes these testers easy to operate. Sensing leads, which operate on either normally-open or normally-closed devices, are connected to the test object. The output current level can be easily pre-set. When the output is initiated, the pre-set output current locks on and the timer starts. When the test set senses a change in state of the test object (NO to NC or NC to NO), the current shuts off and the timer stops. For instantaneous trip tests, the memory feature of the current meter holds the peak current value until reset by the operator.
