T&R Test Equipment is a market leader in the field of current injection
equipment. The range includes single phase units with 50 Amp up to 6000
Amps output capability and three-phase systems up to 200 Amp. All have
true RMS metering, a flexible timing system, and an easy to understand
The 200A-3PH/ED test system provides commissioning and maintenance
engineers with a compact, portable, and flexible system for testing
protective relays, circuit breakers and thermal overloads. The unit is
equally at home testing solid state or electro-magnetic relays, and has
a rating suitable for testing thermal trips.
The 200A-3PH/ED has independent true rms digital metering for each
output with independently selectable ranges. The outputs are isolated
and independently variable and allow the injection of currents up to 200
Amps. The outputs are protected by electronic over-current trips and
The timing system on the 200A-3PH/ED is flexible and exceptionally easy
to use, allowing trip times to be measured to a high degree of accuracy.
Units with auxiliary contacts may be timed using the NC or NO timer
modes, and devices with no auxiliary contacts may be timed using the
current operated mode.
