Three phase-to-neutral voltage monitoring relay with adjustable trip delay. Monitors all three phase-neutral voltages and trips the 1CO 8A@250VAC output when any phase drifts outside setpoints. The adjustable delay prevents nuisance tripping during brief voltage transients. 11 pin plug-in mounting. Commonly used for protecting 3-phase+neutral loads such as IT equipment, lighting systems, and sensitive process controls.
Note: Requires ZB11 11-pin relay base socket (sold separately). For DIN rail retention, add CMAC Spring Clip. For 3-phase (no neutral) voltage monitoring, see the RP30.
