Schneider Electric S33821 is an Under Voltage Release designed for the Masterpact family of circuit breakers, providing automatic trip protection when the control voltage drops below a specified threshold. This Type S release operates with a control voltage range of 100 to 130 VAC/VDC, ensuring reliable disconnection of the breaker under undervoltage conditions. Weighing 5 lb, it is compatible with NT frames and features robust construction for industrial environments. It complies with relevant industry standards for undervoltage protection in power distribution systems. Typical applications include motor control centers, switchgear, and industrial power panels requiring voltage monitoring and safety disconnection.
