Eaton Shunt Trip Release 230 V AC for PKZ0/PKE Circuit Breakers A-PKZ0 (073187)

When a motor protective circuit breaker must be switched off remotely—for example, by an emergency stop button, a fire alarm contact, or a PLC output—a shunt trip release is the component that makes it happen. The Eaton A-PKZ0 shunt trip release is built for exactly this task on Eaton PKZ0 and PKE motor protective circuit breakers. It trips the breaker instantly when 230 V AC is applied to its coil, adding remote tripping capability without replacing the breaker itself.

Who is it for

Electrical planners, panel builders, and maintenance technicians who need to integrate remote tripping into motor protection circuits. It suits industrial control panels, machine safety systems, and building automation where a breaker must be opened from a distance.

Tips

Check the coil voltage before ordering: this version is for 230 V AC 50 Hz supplies. Mount the release on the side of the breaker that gives the cleanest cable routing. The screw terminals accept standard ferrules or solid conductors; tighten to the torque specified in the breaker manual.
