Emergency Stop Button, 22 mm Mounting

The Schneider Electric XB4BS9442 is a maintained-action emergency stop push button designed for industrial control panels. It features a 40 mm red mushroom head with a metal construction and chrome-plated zinc die-cast bezel. The unit mounts in a standard 22 mm cut-out and carries a 10A contact rating at 600V AC.

Suited for Safety Circuits Needing 1NC Contact

This device fits panels requiring a single normally-closed contact block for safety shutdown wiring. Its NEMA 12, 13, 4, 4X ratings and IP66, IP67, IP69, IP69K sealing suit harsh indoor and outdoor environments. Applications needing normally-open contacts, multiple contact blocks, or a different head diameter should consider alternative operators.

1NC Contact Form Determines Wiring Compatibility

The contact form is 1NC, meaning the circuit opens only when the button is actuated. This specific logic is critical for fail-safe emergency stop chains and must match the safety relay or controller input requirements. Verify that your safety circuit design calls for a single normally-closed contact before specifying this unit.

Questions about this item

How often will the 1NC contact block need replacement under normal use?

The contact block is rated for 10 A at 600 V AC with NEMA A600/Q600 designation, so replacement depends on actual switching cycles and load rather than a fixed schedule.

What is the first limit reached during continuous operation of the emergency stop?

The 10 A / 600 V AC contact rating and NEMA A600/Q600 designation define the electrical limit; exceeding this current or voltage will cause the contact to fail first.

Does the button generate noticeable heat or noise when left engaged all day?

As a passive mechanical switch with no internal electronics, it produces no heat or noise of its own while maintained in the engaged position.
