• 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
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 normally-
open 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.
