ABB 1SVR730794R3300 is a CM-PVS.41S three-phase voltage monitoring relay for industrial safety circuits. It monitors 3‑phase voltages in the 3x300–500 VAC range (50/60 Hz) and provides two changeover contacts to drive safety relays or protective contactors. The unit is wired via screw terminals and is designed for integration into machine safety systems that require reliable phase monitoring and fault signaling within ABB's CM‑PVS safety relay family.
