GENERAL SAFETY PRECAUTIONS
HIGH CURRENT
This equipment is capable of providing POTENTIALLY LETHAL VOLTAGES and /or
SEVERE BURNS!
Improper operation or test practices may result in injury or death to the operator or
surrounding personnel.
The operation of High Voltage test equipment should only be performed by personnel familiar
with HIGH VOLTAGE testing and safety procedures. The operator of this equipment must be
aware of all hazards associated with High Voltage testing. The operator is responsible for
himself and others in close proximity of the testing area.
Some General Safety Practices for working with High Voltage Test Equipment have been
listed below for your reference.
•Become familiar with your instrument before performing an actual test
•Know your work area, check that all circuits are de-energized and locked out.
•Never work alone; always work with another qualified worker.
•Mark off entire work area with barriers and warning tape.
•Make all personnel aware of your testing activities.
•Be aware of dangerous conditions that may arise from energizing a test specimen.
•Never modify test equipment, modifications to equipment could introduce an unknown
hazard or hinder a designed-in safety feature.
•DO NOT operate damaged equipment. Remove power, and do not use the equipment
until safe operation can be verified by service-trained personnel.
Phenix Technologies, Inc. assumes no liability for unsafe or improper use of test equipment.

INTRODUCTION
The HC-3 is a portable high current test set built for field and shop use. Designed using the latest technology,
the HC-3 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 HC-3 can be used in many other applications requiring a high current source.
The HC-3 provides a short duration output of up to 4000 amps through a typical 400 ampere 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 HC-3 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 9% (5% of range at 4000 amps) 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.

SECTION 2: DEVICE WARNINGS
1. For safe operation, it is important that the unit be plugged into a properly grounded receptacle.
2. This unit is NOT designed for use to test energized circuits.
3. WARNING: Due to leakage current within the solid-state circuitry, it is STRONGLY RECOMMENDED to
turn control power off when changing the output leads.
4. NEVER connect sense jacks to energized contacts or terminals being injected by test unit.
5. Maintain a minimum of 6 inches between all inlet and exhaust vets and obstructions.

1. INPUT Input cable plugs in here to provide input power.
2. MAIN POWER This controls the input power to the control and the power section and provides power
circuit protection.
3. OUTPUT Protects the variable transformer.
4. F1, F2 Fuses to protect the control circuitry and power supplies.

5. HC ON When pressed, this allows current to flow from the unit (provided that the
output is shorted as through a closed breaker). If this output current exceeds
approximately 9% (5% of 4000A range) of the selected output current range,
the output will be maintained when the switch is released. Also, the TIMER
will begin to run at this point.
6. HC OFF When this is pressed, the output current will cease to flow from the unit.
7. JOG This switch is used when it is desired to preset output current to a specific
level. When pressed, the output current will begin to flow as it would when
HC ON is pressed. The difference is that the TIMER will not begin running in
this mode, and the output current will cease to flow when the switch is
released, regardless of its magnitude.
8. CURRENT CONTROL Controls current level from minimum to maximum of output tap when HC ON
or JOG is activated. Use with JOG to preset current level through test object.
