This Harmony XB4 and Harmony XB5 single contact block uses push-in terminal connections. It features 1 normally open (NO) contact. This contact block allows fast and easy replacement and configuration of your push buttons and selector switches. Compact, it is easily installed and replaced on XB4 or XB5 push-button units and selector switches via a clip assembly and connects to control circuits with push-in terminal connections. It protects operators from unexpected contact with live circuits thanks to its IP20 protection index. 1 million cycle high endurance under 6A load allows less maintenance and damage in your installation. It has clear color scheme for NO contact block types. Vibration resistant push-in connection terminals ensure high vibration resistance making product suitable installation on high impact machine. This contact block is sold by 5. Harmony delivers an innovative and ergonomic design that improves the reliability of panels, machines, and processes.
