| MODEL 2744 3-Phase Over Current Monitor For Motor Jams |
| Series Description: 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 5A, 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. |
