Din rail Voltage Protection Device

Surge and permanent overvoltage protection for electrical cabinets

Din-Rail voltage protection devices are modular designed mounted in electrical cabinets. Devices trip the connected shunt release when they detect a permanent overvoltage or under voltage. The shunt release causes the circuit breaker to trip, protecting the equipment installed downstream.
