ABB Thomas and Betts TRIB-250 Insulated Bushing

Description:

The ABB Thomas & Betts TRIB250 Insulated Bushing is used to provide a smooth, insulated bearing surface at the end of 2-1/2-inch rigid or intermediate metal conduit (IMC), protecting conductors from abrasion during installation and operation. Commonly installed in commercial buildings, industrial facilities, electrical distribution systems, and manufacturing plants where rigid conduit or IMC is used for power and control wiring. Maintenance electricians, contractors, and system integrators use this insulated bushing for new installations, equipment maintenance, retrofits, and replacement of worn or damaged conduit bushings.

Applications:

The Thomas & Betts TRIB250 is a threadless, pop-on insulated bushing manufactured from high-impact thermoplastic for long-lasting durability and electrical insulation. Its push-on design allows fast installation without screws while providing a well-rounded insulating surface that reduces conductor damage during wire pulling and protects conductors while in service. The bushing is suitable for use with 2-1/2-inch rigid metal conduit (RMC) and intermediate metal conduit (IMC) in commercial, industrial, utility, and OEM electrical installations.
