273-10-120
Single Phase Over/Under Current Monitor2 to 10ARead moreThe Model 273 Single Phase Current Monitor is a single set-point sensor. It can be used as either an over current or under current sensor, depending on the contacts used. This device can directly monitor AC currents in the range of 0.5 to 5 amps: or 2 to 10 amps, 50 to 400 Hz. Matching transformers are available to extend the use of the monitor to most any range. The current being monitored can be of any voltage, up to the rating of the socket. An LED indicator is provided to show when the relay is energized. The Model 273 is available for either 24 VAC or 120 VAC supply voltages.
Model 273-5 is UL Recognized and CSA Certified. All versions use a standard 8-pin socket.

A2732
Single Phase Over/Under Current Monitor1 - 5ARead moreThe 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.
