Allen-Bradley NSB312IN Threaded Insulating Bushing

Description:

The NSB 3-1 2-IN Insulating Bushing is used in electrical conduit systems to protect conductors from abrasion where conduit enters electrical enclosures and raceways. Commonly installed in control panels, switchgear assemblies, junction boxes, and commercial or industrial electrical installations requiring conductor protection. Maintenance teams, electricians, and system integrators use this part for replacement, retrofit, and new conduit installations to help prevent wire insulation damage and maintain safe electrical operation.

Applications:

The NSB 3-1 2-IN Insulating Bushing is commonly used in conduit and raceway systems where conductors pass through threaded conduit terminations. It provides a protective barrier between wiring and metal conduit edges, helping extend conductor life and improve installation safety in electrical systems.
