The Schneider Electric EZESHT100AC is a shunt trip release from the EasyPact range, designed for the EZC250 and EZCV250 circuit breaker frames. It operates on a 100...120 V AC control circuit at 50/60 Hz, with a tripping threshold of 0.7 Un.
This part is classified as Obsolete per the manufacturer.
The shunt trip release is a voltage release type used for remote tripping of the breaker via a control signal. The 0.7 Un operating threshold means it will trip when the control voltage drops to 70% of the rated value, providing undervoltage protection. Connection is via lead wires, which simplifies panel wiring compared to terminal-block variants.
