That makes it the go-between from the mains to the motor contactor or drive enable circuit: if a phase drops or the rotation is wrong, the relay opens and the load stops before it single-phases or reverses. ## Sourcing and availability for the BOM line If you are replacing an older CM-PSS variant, confirm the pinout and voltage range against the existing wiring; the series designation matches, but the suffix letter can change the trip thresholds.","metaTitle":"ABB 1SVR730784R2300 CM-PSS.31S Three-Phase Monitoring Relay","metaDescription":"ABB 1SVR730784R2300 CM-PSS.31S three-phase monitoring relay, current lifecycle stage.
