Shunt trip release for EZC100 — 48 V DC
The Schneider Electric EZASHT048DC is a shunt trip release (SHT) for the EasyPact EZC100 molded-case circuit breaker family. It operates on a 48 V DC control circuit and trips the breaker when the control voltage drops to 0.7 Un (approximately 33.6 V DC), providing remote or undervoltage protection for control circuits.
Schneider Electric lists EZASHT048DC as obsolete.
Wiring and integration
Connection is via lead wires — no terminal block, so plan for a junction point or DIN-rail terminal strip inside the panel. The 48 V DC coil draws power from the control circuit; verify the supply can deliver the inrush without dropping below the 0.7 Un threshold during a fault condition.
