ENTES-FR-02 Motor-Phase-Protection Relay

General Information

The phase sorting relay has been developed to control the order of the 3 phases supplying the motors. If the R, S and T phases are in the correct order, the light on the front panel turns on (ON). If the phase sequence is incorrect, the light goes out and the output relay leaves (OFF). The phase sequence relay is used for the protection of 3-phase motors of systems such as air compressors and elevators. The FR-02 is recommended for use in places where engine inversion may cause damage to people or systems.
