Phenix Technologies’ High Current Test Sets provide a short duration output through a typical molded-case circuit breaker when an instantaneous trip element must be tested. Sufficient current is available for testing time delay characteristics of motor overload relays and molded-case circuit breakers.
The unique auto-sensing feature makes the test set easy to operate. Sensing leads, which operate on either normallyopen or normally-closed (non-energized) devices, are connected to the test object auxiliary contacts or open breaker pole. The output current level can be easily preset. When the output is initiated, the preset output current locks on and the timer starts. When the test set senses a change in state of the test object auxiliary contacts (NO to NC or NC to NO), the current shuts off and the timer stops. For instantaneous trip tests, the memory feature of the currentmeter holds the peak current value until reset by the operator.
