3-Phase Monitor Relay • Type: Reversal, Loss, Voltage • Coil Voltage: 110/120 VAC • Contact Configuration: SPDT (1 Form C) • Mounting: Base • Contact Current: 10 Amps
Series: Model 158(R)
Series Description:
The Model 158 continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, the Model 158 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 electro-mechanical 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.
The Model 158 does not require a neutral connection, and can be used with Wye or Delta systems. Four versions cover 120V, 208/240V, 480V (60Hz) and 380V (50Hz). Voltage ranges are sufficient to allow for proper adjustment to existing conditions. A front-mounted L E D failure indicator is provided.
The “R” versions of the Model 158 Monitor have an additional LED indicator for RESTART, and a 5 minute short cycle timer, to delay restarting the motor.
The Model 158 can be DIN Rail or Surface Mounted.
