The 200A-3PH Mk2 Secondary Current Injection test system provides commissioning and maintenance engineers with a compact, portable and flexible system for the testing and timing of protective relays, circuit breakers and thermal overloads. The unit is equally at home testing solid state or electro-mechanical relays, and has a rating suitable for testing thermal trips.

The 200A-3PH Mk2 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 200A. The outputs are protected by electronic over-current trips and fuses.

The timing system on the 200A-3PH Mk2 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.
