Contact Block · 22.5 mm · 1NC Front Mount Screw Terminal · Eaton E22B1
What this product is for
The Eaton E22B1 is a 22.5 mm contact block used behind compatible E22 series pushbuttons and indicating lights. It provides 1 normally closed contact for control circuits in industrial panels and operator stations.
Use for
Use for replacement or new assembly of 22.5 mm pilot devices where a 1NC contact is required. Common applications include stop circuits, interlocks, machine controls, and motor control panel devices.
Avoid for
Avoid for applications requiring normally open contacts, illuminated operators by themselves, or use with non-compatible pilot device families. Confirm device series and mounting style before ordering.
Best for
Best for electricians and panel builders needing a front-mount, screw-terminal contact block for Eaton E22 heavy-duty 22.5 mm control devices.
Installed in
Typically installed in industrial control panels, OEM machinery, motor control stations, and equipment operator interfaces.
Why this product exists
This contact block lets you configure or replace the switching function of an E22 operator without replacing the full pilot device assembly. A 1NC block is commonly used where the circuit remains closed until the operator is actuated.
Compared with similar products
Compared with a 1NO block, this version provides 1 normally closed contact. Compared with complete pilot devices, this is the rear contact element only and is intended for use with compatible Eaton E22 22.5 mm operators.
