  • Adjustable Test Stab Set

    ETI Precision

    The ETI adjustable test stab set may be used with your high-current circuit breaker testers to maximize efficiency and convenience for testing multiple breakers. Our stab system allows your technicians to test breakers in-place and avoid jacking breakers up or down for testing. By combining mobility and flexibility into one simple system, this stab set is a proven improvement over conventional designs. The components in the adjustable stab set are made of 120 pounds of 110 copper.

  • Advanced Primary Injection Test Set

    PI-2500 - ETI Precision

    The PI-2500 is a versatile and technologically advanced primary injection tester capable of testing circuit breakers up to 2000 amperes frame size. It incorporates a low-impedance output transformer with dual secondaries to provide optimal impedance matching to a wide range of breaker sizes. High-capacity internal fan cooling allows maximum utilization of the output transformer and faster recovery after overload conditions. It is housed in a rugged aluminum frame enclosure with removable sides allowing easy access to all internal components to facilitate ease of service and maintenance. The output of the test set is controlled by means of a proven SCR controller. This provides precise initial phase angle control to reduce DC offset for inductive loads and more consistent pulse currents.

  • Primary Injection Test Set

    PI-6000 - ETI Precision

    The PI-6000 is a rugged & durable primary injection test set capable of testing circuit breakers up to 6,000 amperes frame size. It incorporates an output transformer with dual primaries to facilitate its use on power sources of 480 VAC as well as 208-240 VAC. The unit also includes dual secondaries to provide optimal impedance matching to a wide range of circuit breaker sizes. An internal voltage sensor automatically configures the AC control power section to be energized only when properly configured for the applied voltage.

  • Portable Circuit Breaker Tester

    PI-1600 - ETI Precision

    The PI-1600 Circuit Breaker Tester incorporates modular design and flexibility to provide unequaled capability in a portable package. The PI-1600 test set is two testers in one, incorporating the PI-800 and PI-AUX. The PI-800 section can be used alone, on 120 or 240 VAC supplies, generating continuous current of 400, 800, amps at 4.2 kVA, with peak output to over 10x. When configured for the PI-1600, the PI-AUX output unit is connected in series or parallel to the PI-800. The PI-AUX boosts total power to 9.8KVA, and allows testing of draw-out breakers and MCB’s to 1600 Amps. The units are housed in rugged interlocking suitcase-size enclosures. Each piece weighs no more than 125 pounds, allowing one-person hand truck mobility. Basic operation is very simple, and the proven MAC-21 control instrumentation provides optimal output control and measurement. The MAC-21 instrumentation is supplied in a separate rugged portable case, interlocks on top of the PI-800, and connects to a cable in the rear of the test set.

  • Modular Circuit Breaker Test Set

    PI-800 - ETI Precision

    The PI-800 Circuit Breaker Test System incorporates modular design and flexibility to provide unequaled capability in a portable package. The PI-800 generates continuous current of 800 amps at 4.2 kVA, with peak output to over 10x, on 120 or 240 VAC supplies. The units are housed in rugged interlocking suitcase sized enclosures. Each piece weighs no more than 125 pounds, allowing one person hand truck mobility. Basic operation is very simple, and the proven MAC-21 instrumentation provides optimal output control and measurement.

  • Transforming Analog Circuit Breaker Testers

    MAC-21 - ETI Precision

    The MAC-21 uses proven microprocessor and A/D converter technology to provide real-time waveform analysis. This ensures accurate true-RMS readings of current pulses, even with DC offset and distortion, which are typical in primary injection testing. Intelligent threshold algorithms provide accurate trip time measurement. Integration of measurement and control functions allow advanced features such as preset on times, auto ranging, and optional printer or computer interface.

  • Primary Injection Testers

    AT-10B - ETI Precision

    ETI’s AT-10B autotransformer steps-down 480V outputs to 240V outputs. This portable autotransformer allows ETI’s PI-1600 or PI-800 circuit breaker testers to be used at full-capacity on 240 and 480 VAC lines. The unit provides 240 VAC at 10 kVA, is housed in a rugged ABS enclosure approximately 22″ x 11″ x 22″, and weighs less than 125 lbs.

  • Primary Injection Circuit Breaker Tester

    PI-5000 - ETI Precision

    The PI-5000 is composed of the PI2500 and the AUX-5000 auxiliary output unit, which when combined gives the unit the capability of testing 4000 ampere breakers, with essentially the same specifications as the proven PI-4000B. The auxiliary unit is smaller than the PI2500, so it can also be maneuvered easily in tight spaces, or lowered into shafts and manholes that would not be possible with a larger single piece unit.
