2744-120
The Model 2744 3-Phase Over Current Monitor is designed to monitor the current level of a three-phase line or to compare the currents of three single-phase lines. If one or more current inputs rises above the trip level after the start delay has expired, the internal relay will de-energize. An adjustable start delay of 5 to 15 seconds will prevent nuisance tripping on start up. The current trip point is adjustable from 1 to 5 amps, and matching current transformers are available to extend the current range of the monitor. The Model 2744 will automatically reset when the current fault is corrected. An external manual reset can be added by installing a normally closed switch between the terminals marked RESET. -

275-5-120-A
The Model 275 Single Phase Current Monitor is designed for monitoring alternating current in the range of 1-5 amps, at 50 to 400 Hz. The Model 275 provides a contact transfer when the set current level is exceeded for a period longer than the time delay. The OVER-CURRENT indicator illuminates immediately. After the time delay, the TRIPPED indicator lights and the relay contact transfers. This device can directly monitor AC currents in the range of 1 to 5 amps; 50 to 400 Hz. Matching transformers are available to extend the use of this monitor to most any current range. The Model 275 is available with automatic or manual reset. Operating power is supplied by separate 24 or 120 volt power supply. -

A2722
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. -
A2732
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. -
