Two-Pole Switch Integrates Under-Voltage Release

Ensuring operator safety, the UP1 two-pole appliance switch features an under-voltage trip release that prevents uncontrolled restarts by monitoring and tripping under conditions of extreme voltage drop or when the supply voltage is interrupted. When supply voltage returns in full, the machine or equipment must be manually switched on again. Essentially, the UP1 with pushbutton or rocker actuation is a circuit breaker with under-voltage 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. Pricing starts at about $16 each/100.
