    Current Unbalance Detector
    1 - 5A

    The Model 2722 Current Unbalance Detector is designed to monitor 3-phase AC current (or compare three single-phase AC currents). A solid-state electronic sensing circuit drives an internal DPDT relay which energizes during normal, balanced conditions. An unbalanced condition will cause the relay to drop out. The Model 2722 accepts current inputs up to 5 amps and will consider zero amps as balanced (relay stays energized), making the device suitable for use with 3-phase heaters. The Model 2722 has adjustments for percent of unbalance and time delay before tripping. It will automatically reset upon restoration of correct current balance, or a normally-closed momentary switch can be connected for a manual reset. External CT’s can be used to extend the operating current range.

    Single Phase Over/Under Current Monitor
    1 - 5A

    The Model 2732 Single Phase Current Monitor is designed to continuously monitor single-phase AC current. It consists of a solid-state sensing circuit driving an internal electromechanical relay. The Model 2732 has two operating modes: over-current sensing or under-current sensing. The operating mode is selected by means of a slide switch on the monitor. When operating voltage is applied, and the current level is correct according to the operating mode, the relay will energize. A fault condition will cause the OVER/UNDER LED on the monitor to illuminate, and the trip delay will begin. If correct current is restored, the relay remains energized. If current is not restored during the delay period, the relay will de-energize and the red TRIP indicator will illuminate. The Model 2732 has three reset configurations: automatic, manual (add jumper), or manual remote (add switch). The standard model, as provided, will reset automatically.
