Bussmann FLRM Shaft-Operated Flange Mechanism for NEMA 1, 3R, and 12 Disconnect Switches

Bussmann FLRM Shaft-Operated Flange Mechanism for NEMA 1, 3R, and 12 Disconnect Switches

The Bussmann FLRM is a shaft-operated flange mechanism engineered for direct mechanical actuation of compatible disconnect switches. Supplied complete with its operating shaft, the FLRM is built for use with NEMA 1, 3R, and 12 rated disconnect switches, making it a dependable component for indoor and outdoor enclosure applications where reliable external switch operation is required. With a compact footprint of 32 IN in length, 3.5 IN in height, and 3 IN in width, and a lightweight 3.64 LB construction, the FLRM integrates cleanly into panel and enclosure designs while supporting consistent, code-compliant switch actuation on the job. Electricians and panel builders can specify the FLRM as a drop-in flange mechanism when a shaft-operated handle assembly is needed for a NEMA 1, 3R, or 12 rated disconnect switch enclosure.

Key Features
