Contact Block · - 1NC normally closed - positive opening - 22.5 mm control device - ITC Electrical RB2-BE102T

What this product is for

This contact block is used to add or replace a normally closed contact in 22.5 mm industrial control stations, pushbuttons, and selector assemblies. It is commonly installed in control panels, machinery interfaces, and operator stations where an NC contact is required for stop, interlock, or status functions.

Use for

Use for panel-mounted control devices that require 1NC contact action, including stop circuits, interlocks, and auxiliary control logic. It is typically selected by electricians and panel builders servicing industrial and light commercial control panels.

Avoid for

Avoid using this part where a normally open contact, stacked multi-contact arrangement, or a different mounting style is required. Do not assume cross-compatibility with other 22 mm or 22.5 mm operator families without confirming the exact device series.

Best for

Best for maintenance replacements and new panel builds using ITC RB2 series control devices. Positive opening NC contacts are commonly chosen where reliable circuit interruption is important in control logic.

Installed in

Installed in industrial enclosures, OEM control panels, machine panels, and operator stations. Typical applications include manufacturing equipment, process skids, and panel shop assemblies.

Why this product exists

This contact block provides the NC switching element behind a compatible operator head so panel builders can configure the required control function without replacing the full device assembly.

Compared with similar products

Compared with a 1NO block, this 1NC version is used where the circuit is closed in the normal state and opens when actuated. Compared with combined contact blocks, a single 1NC block is the simpler choice when only one auxiliary contact is needed.

Specifications

• Product type: Contact block
• Contact configuration: 1NC normally closed
• Operation: Positive opening on NC contact
• Device family: ITC RB2 22.5 mm control devices
• Typical application: Pushbuttons, selector switches, and control stations
