Time Mark Phase Loss Relay

When correct voltage and phase rotation are applied the internal relay will energize.

Time mark phase loss relay.

The model 269 is independent of the system load and may be used on any horsepower motor. This device features a solid state voltage and phase angle sensing circuit which drives a spdt output relay. When properly adjusted the model 158 monitor will detect phase loss on a loaded motor even when regenerated voltage is present. The model 259 3 phase monitor is designed to protect individual 3 phase equipment and motors or in conjunction with shunt trip breakers.

A fault condition phase loss phase reversal or low voltage drops out the relay and lights the led failure indicator. The model 263 continuously monitors 3 phase power systems for phase loss low voltage and phase reversal. This device features a solid state voltage and phase angle sensing circuit which drives a spdt output relay. This device consists of a solid state voltage and phase angle sensing circuit driving an electromechanical relay.

This device consists of a solid state voltage and phase angle sensing circuit driving an electromechanical relay. When correct voltage and phase rotation is applied an internal dpdt relay energizes. The model 259 will detect a phase loss condition. When phase sequence is correct and the voltage.

This device consists of a solid state voltage and phase angle sensing circuit driving an electromechanical relay. Applying correct voltage and phase rotation energizes the relay. When correct voltage and phase rotation are applied the internal relay will energize. This device consists of a solid state voltage and phase angle sensing circuit driving an electro mechanical relay.

Over under 3 phase monitor continuously monitors 3 phase lines for high voltage low voltage phase loss or phase reversal. The model 257 continuously monitors 3 phase power lines for abnormal conditions. The device consists of a solid state voltage and phase angle sensing circuit driving an electromechanical relay with one spdt and one spst contact. When properly adjusted a fault condition will cause the relay to de energize even when regenerated voltage is present.
