S29402 Schneider Electric Circuit Protection Accessories

Square D by Schneider Electric S29402 is a coil designed for undervoltage release and tripping functions (MN). It operates with a control voltage of 12Vdc. Specifically, it instantaneously opens the circuit breaker when the undervoltage trip supply voltage falls to a range between 35% and 70% of its rated control voltage. The circuit can close when the supply voltage of the undervoltage trip reaches 85% of the rated control voltage.
