Abb 18RA-250T Insulated Male Disconnect Terminal Block

Product Description

The ABB 18RA-250T is an insulated male disconnect terminal block rated for 22 to 18 AWG wire range. It provides a reliable, insulated connection point for low-voltage wiring in control panels, junction boxes, and field wiring applications. The male disconnect design allows for quick, tool-free circuit disconnection, which simplifies troubleshooting and equipment servicing. Licensed electricians and panel builders typically install this component during control wiring assemblies. The insulated body protects against accidental contact with adjacent conductors, making it well suited for dense terminal strip layouts in commercial and industrial enclosures.

This terminal block is commonly used in electrical control panels, HVAC equipment wiring compartments, and industrial automation cabinets where organized, disconnect-capable terminations are required. It is appropriate for both new panel builds and retrofit wiring projects where a serviceable, insulated disconnect point is needed at the terminal strip level. The 22 to 18 AWG wire range makes it compatible with typical low-voltage control wiring found in commercial HVAC and light industrial settings.

Key Features

• Insulated male disconnect design for safe, organized circuit termination
• Wire range of 22 to 18 AWG suits standard low-voltage control conductors
• Allows quick circuit disconnection without additional tooling
• Insulated body reduces risk of incidental contact between adjacent terminations
• Compact form factor fits standard terminal strip and DIN rail panel layouts

Compatibility

Designed as an OEM-style replacement or new-installation component for insulated male disconnect terminal block applications accepting 22 to 18 AWG conductors.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lock out the panel or enclosure before servicing any terminal connections. Confirm wire gauge falls within the 22 to 18 AWG rated range before terminating conductors. Do not exceed the rated wire size, as oversized conductors can damage the insulated disconnect body.
