The AC-PRO ® Trip unit is a solid state, true RMS sensing overcurrent device for use on 600 volt class circuit breakers. The AC-PRO ® comes standard with Long-Time, Short-Time, Instantaneous, Ground Fault, and Phase Unbalance protections. Each of these protective features can be turned on or off at any time except for the Long-Time setting.
The AC-PRO is a state of the art, micro-controller based trip unit for use on three phase, 600 Volt class, AC circuit breakers. Models are available for use on 60 Hz, 50 Hz, 40 Hz, and 25 Hz systems. The AC-PRO is a digital trip unit that uses a micro-controller and a 16-character liquid crystal display (LCD).
The external connections are made to the top of the AC-PRO trip unit (or the left or right side for the vertical versions). Figure 4.1 AC-PROTM Top View The breaker wiring harness connects the trip unit to the CTs and actuator. The wiring harness plugs into the 10-pin connector on the top of the trip unit and is retained with two screws.
