3-Phase Monitor Relay • Type: Reversal, Loss, Voltage • Coil Voltage: 110/120 VAC (400 HZ) • Contact Configuration: SPDT (1 Form C) • Mounting: Plug-in - 8 Pin Octal • Contact Current: 10 Amps
Series: Model 258
The Model 258 continuously monitors 3- phase power lines for abnormal conditions. When properly adjusted, the Model 258 Monitor will detect phase loss on a loaded motor even when regenerated voltage is present.
This device consists of a solid-state voltage and phase-angle sensing circuit, driving an electromechanical relay. When correct voltage and phase rotation are applied, the internal relay will energize. A fault condition will de-energize the relay. When the fault is corrected, the monitor will automatically reset (a manual reset version is also available).
The Model 258 3-Phase Monitor does not require a neutral connection and can be used with Wye or Delta systems. Voltage ranges are sufficiently wide to allow for proper adjustment to existing conditions. Both “TRIP” and “NORM” condition indicators are provided to aid in adjustment and system trouble-shooting.
