Contact Block · 1NO · For Metal Enclosures · ITC Electrical RB2-BE101BM

What this product is for

This is a base-mounted normally open contact block used with compatible ITC 22.5 mm metal enclosure pushbutton and selector switch assemblies. It adds one NO contact to the operator station for industrial control and panel applications.

Use for

• Replacement of an existing NO contact block in a metal control station
• Building up pushbutton or selector assemblies in machine control circuits
• Start, enable, reset, or signalling functions where a normally open contact is required

Avoid for

• Applications requiring a normally closed contact block
• Plastic enclosure assemblies when the metal-enclosure version is specified separately
• Use outside the compatible 22.5 mm operator family without confirming fitment

Best for

Electricians, panel builders, and maintenance teams replacing or configuring ITC metal enclosure control stations with a straightforward 1NO contact arrangement.

Installed in

Typically installed behind the operator in metal pushbutton stations, selector switch enclosures, and industrial control panels. This contact block is commonly used as a base-mounted contact in compatible metal enclosure assemblies.

Why this product exists

It provides a simple way to add or replace a normally open switching contact in a metal operator station without replacing the full control device. This helps maintain standard control functions and simplifies service work.

Compared with similar products

Compared with a normally closed version, this 1NO block closes the circuit only when the operator is actuated. Compared with multi-contact assemblies, this single-contact block suits simpler control points or staged build-ups where only one NO contact is needed.

Typical guidance: single NO blocks are commonly used for start or permissive functions, but actual control logic depends on the circuit design, relay logic, PLC input requirements, and local electrical code.
