Switch with built-in undervoltage release protects operator safety
SCHURTER UP1 series 2-Pole appliance switch with built-in undervoltage trip release prevents uncontrolled restarts by monitoring and tripping under conditions of extreme voltage drop, or when the supply voltage is interrupted. Even when the supply voltage returns in full, the machine or equipment does not automatically restart, but must be manually switched on again. The UP1 with pushbutton or rocker actuation is a circuit breaker with undervoltage protection, and without overload protection. The pushbutton version is available in both snap-in and screw-on (flange) mounting, while the rocker version is designed for snap-in mounting.
