HC-2
1-1
SECTION 1: TECHNICAL SPECIFICATIONS
The HC2 is a portable high current test set built for field and shop use. Designed using the latest technology,
the HC2 combines a variable high current output with appropriate controls and instrumentation for testing
thermal, magnetic, and solid-state motor overload relays, molded-case circuit breakers, and ground fault trip
devices. The HC2 can be used in many other applications requiring a high current source.
The HC2 provides a short duration output of 2000 amps through a typical 200 amp 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 HC2 easy to operate. Sensing leads, which operate on either
normally-open or normally-closed (non-energized) devices, are connected to the test object auxiliary or non-
energized contacts. 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
auxiliary contacts (NO to NC or NC to NO), the current shuts off and the timer stops. If set to sense current,
unit will shut current off at approximately 10% of range switch setting of currentmeter when test object goes
open. For instantaneous trip tests, the memory feature of the currentmeter holds the peak current value until
reset by the operator.
