ABB CM-PVS.41S Three-Phase Monitoring Relay

The three-phase monitoring relays CM-PVS.x1 monitor the phase parameters phase sequence, phase failure as well as over- and under voltage.
All devices are available with two different terminal versions. You can choose between the proven screw connection technology (double-chamber cage connection terminals) and the completely tool free Easy Connect Technology (push-in terminals).

• Rated control measuring voltage: 3x 300-500V AC
• Connection technology: Screw terminals
• Monitoring of three-phase mains for phase sequence (can be switched off), phase failure, over and Under voltage
• TRMS measuring principle
• Powered by the measuring circuit
• Precise adjustment by front-face operating controls
• Tool free mounting on DIN rail as well as demounting
• 3 LEDs for the indication of operational states
