Schneider Electric 10A 600V N.O. CONTACT BLOCK W MOUNTING COLLAR Contact Block

Schneider Electric Harmony XB4 22 mm add-on contact block, model ZB4BZ101, provides one normally-open (NO) contact in a compact, single-pole module that mounts with the accompanying mounting collar to a compatible Harmony XB4 push-button base. It carries a 10 A, 600 V rating and uses screw-clamp terminals for secure wiring, making it suitable for expanding discrete inputs in control circuits, PLC interfaces, interlocks, and safety logic without changing the primary operator. This NO contact block is part of the ZB4 family and is designed to pair with 22 mm Harmony components, delivering a reliable auxiliary contact when an additional NO path is required in your control circuit.
