Surface-Mount Motor Voltage Monitors
Protect electric motors from phase loss, phase reversal, overvoltage, undervoltage, and voltage imbalance. Also known as voltage-monitoring relays, these monitors cut power to a motor when a fault occurs.

Socket-Mount Motor Voltage Monitors
Plug these monitors into relay sockets for fast installation and replacement. They protect electric motors from phase loss, phase reversal, overvoltage, undervoltage, and voltage imbalance. Also known as voltage-monitoring relays, they cut power to a motor when a fault occurs.
Relay sockets (sold separately) mount to 35 mm DIN rail or flat surfaces.
