Eaton Z-HK contacto auxiliar 1NO+1NC 8A 250V AC para série xPole 248432

When a circuit breaker trips, you need to know about it. The Eaton Z-HK auxiliary contact solves that problem by providing a reliable signal contact that mirrors the status of your protective device. It mounts directly onto the side of Eaton xPole MCBs, RCDs, and RCBOs, giving you a clear electrical indication of whether the main contacts are open or closed.

Who is it for

This auxiliary contact is for panel builders, electricians, and maintenance technicians who need remote status monitoring or control interlocking in distribution boards. It is especially useful in industrial control systems, building automation, and any application where a circuit breaker's state must be communicated to a PLC, indicator lamp, or alarm system.

Main features

• 1 normally open (NO) and 1 normally closed (NC) contact for versatile signaling

Tips

Always verify that the auxiliary contact is fully engaged with the main device to ensure reliable switching. For DC applications, respect the lower current rating to prevent contact welding. When wiring, use appropriate ferrules and torque the screws to the manufacturer's recommendation.
