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.
