Contact Block 22 mm 1NC Momentary

This Schneider Electric ZB2BE102 contact block is a 22 mm panel-mount component designed for industrial control panels. It provides a single normally closed momentary contact for machine manufacturers and control system integrators building or maintaining operator interfaces. The modular Harmony design allows flexible assembly to meet specific application requirements in sectors such as automotive, textiles and timber.

Snap-fit locking with single-screw tightening

An ingenious locking system joins the snap-fit head and body, secured by a single screw for easy yet secure mounting on a fully metal collar. Shake-proof connection screws eliminate the need for periodic retightening, while the robust construction withstands high-pressure cleaning, dust and extreme temperatures in everyday industrial environments.

One normally closed momentary contact

The block delivers exactly one normally closed momentary contact, making it suitable only for circuits that require this specific switching function. Buyers who need normally open contacts, multiple poles or maintained switching must select a different module.

Questions about this item

What does the 22 mm mounting size mean for panel cut-out dimensions?

The 22 mm size matches the standard industrial panel cut-out for Harmony series operators, so the contact block fits a 22 mm diameter hole in the control panel.

What hardware is required to secure the contact block to the panel?

The block uses the Harmony snap-fit head and body that lock onto a metal mounting collar; a single screw on the collar tightens the assembly without extra brackets.

How is the momentary 1NC contact block installed, and what step is often missed?

Snap the head onto the body, slide the assembly through the 22 mm cut-out, fasten the collar screw, then wire the normally-closed terminal; the step often missed is fully tightening the collar screw to lock the snap-fit securely.
