Industrial 22 mm Contact Block
The Schneider Electric ZENL1111 is a single normally-open screw-clamp contact block built for 22 mm Harmony push-button and selector-switch assemblies. It suits control-panel builders and maintenance engineers who need a reliable low-load or high-power switching element in industrial automation environments.
Thermals Noise and Power Draw
The block uses shake-proof connection screws that eliminate the need for periodic retightening, keeping contact resistance stable over long service intervals. No active cooling or moving parts are present, so the device operates silently and adds negligible heat to the enclosure during normal operation.
Upgrade Path and Compatibility
The module snaps onto Harmony XB4, ZB4, XB5 or ZB5 metal or plastic operators and mounts on a fully metal collar with a single screw, letting teams replace worn contacts or expand existing stations without rewiring. It is not suited for installations that require a different contact configuration, a non-22 mm mounting footprint, or tool-less spring-clamp terminals.
Highlights
- 1NO contact for simple control logic
- 22 mm modular size fits standard panels
- Screw-clamp terminals resist vibration loosening
- Snap-fit head and body enable quick assembly
- Metal mounting collar provides robust installation

Questions about this item
How do I install the ZENL1111 contact block into a 22 mm Harmony push button station?
Snap the contact block onto the operator head, then secure the single mounting screw on the metal collar to lock it in place.
What maintenance will the ZENL1111 contact block require over time?
The shake-proof connection screws eliminate the need for periodic retightening, so no routine screw maintenance is needed.
What is the first limitation you hit when running the ZENL1111 continuously at high load?
The block is rated for both low-load and high-power applications, but sustained high-current use will eventually be limited by the contact block's thermal capacity.
