22 mm Emergency Stop Station

This Schneider Electric XALK178EH7 is a wall-mounted control station with a single 40 mm red mushroom-head operator. It provides a maintained emergency-stop function rated for 10 A at 600 V AC and 2.5 A at 24 V DC. The enclosure carries NEMA 1, 2, 3, 4, 4X, 12 and 13 ratings plus IP66, IP67, IP69 and IP69K protection.

Installation notes

The unit mounts on a flat surface and accepts an ISO M20 cable hub for feed-through wiring. Contacts are 1NO/1NC screw terminals; strip conductors to the length recommended by the terminal specification. Overtightening the gland can damage the plastic housing, and misaligned conduit entries may compromise the IP69K seal.

Pre-order checks

Verify that the 22 mm mounting cut-out and 2.67 in by 2.67 in footprint fit your panel layout. Confirm the 3.6 in depth clears internal components and that the A600/Q600 contact rating matches your control-circuit voltage and current. Ensure the maintained-action logic suits your safety-circuit design.

Questions about this item

How can I confirm the Schneider Electric XALK178EH7 is working correctly after installation?

Press the 40 mm red mushroom head to latch it, then verify the 1NO/1NC contacts change state with a multimeter; the IP66, IP67, IP69 and IP69K ratings mean the enclosure remains sealed during the test.

What comes in the box with the Schneider Electric XALK178EH7 and what must I source separately?

The station ships as a complete 22 mm control station with the maintained mushroom operator and 1NO/1NC contact block installed; you only need to supply the ISO M20 cable gland and mounting hardware for the wall.

Which version of the Schneider Electric XALK178EH7 should I choose for a 24 V DC safety circuit?

The contact block is rated 2.5 A at 24 V DC (Q600) and 10 A at 600 V AC (A600), so this single model covers both voltage levels without a separate variant.
