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.

Start delay of 5 to 15 seconds and adjustable trip point from 1 to 5 amps. (read more)
