What this product is for

The Eaton E22B2 is a standard contact block used with compatible 22.5 mm heavy-duty non-metallic pilot devices. It adds one normally open contact for control circuits, signalling, and panel-mounted operator assemblies.

Use for

Use for industrial control panels, machine panels, operator stations, and replacement work where an Eaton E22 series 1NO contact block is required. It is suited to pushbuttons and selector switch assemblies that need screw terminal field wiring.

Avoid for

Avoid using this as a standalone switching device or where a normally closed contact is required. Do not assume compatibility with other pilot device families without confirming the operator series and mounting arrangement.

Best for

Best for electricians and panel builders maintaining or assembling 22.5 mm Eaton pilot devices in industrial and light commercial control applications. It is a practical choice when you need one NO contact and straightforward screw termination.

Installed in

Typically installed behind a 22.5 mm panel operator in control cabinets, OEM equipment, motor control stations, and machine interface panels. Panel cutout size is typically 22.5 mm, approximately 0.89 in.

Why this product exists

This contact block lets contractors and panel shops configure pilot devices for the required circuit function without replacing the full operator assembly. A 1NO block is commonly used for start commands, permissive circuits, and signalling logic, depending on the control scheme.

Compared with similar products

Compared with combination or multi-contact blocks, this model provides a single normally open circuit only, which helps when space, wiring simplicity, or exact replacement matters. If your circuit needs a break contact, interlock, or additional poles, a different contact arrangement will be required.
