Bryant 4901L Locking Switch
The Bryant 4901L is a single-pole locking wall switch rated for 20 A at 120/277V AC. It suits industrial facilities that require key-controlled circuit operation to prevent unauthorised toggling of lighting or motor loads up to 2 hp.
Build and Wiring
The switch body meets NEMA WD-1 and UL20 standards and features a quiet mechanism with screw-terminal connections that accept back or side wiring. A straight-key locking style secures the actuator, while the 1.7 in. overall height fits standard industrial wall boxes.
Decisive Specification
The 20 A, 120/277V AC rating with a 2 hp motor load capacity determines whether this switch matches the circuit protection and load requirements. Installations needing a different current rating, voltage class or non-locking operation should select an alternative device.

Questions about this item
What does the 120/277V AC rating cap in practice for the Bryant 4901L?
The switch handles up to 20 A on 120 V or 277 V AC circuits, with a 2 hp motor load limit per the NEMA WD-1 and UL20 listing.
What wall-box depth does the 1.7 in. tall Bryant 4901L require?
The 1.7 in. overall height fits standard 2 in. deep commercial boxes; allow extra room behind the device for back-wired screw-terminal connections.
How is the straight-key locking mechanism engaged on the Bryant 4901L, and what step is often missed?
Insert the straight key and turn to lock the toggle in the ON or OFF position; the step often missed is verifying the key is fully rotated so the actuator cannot be moved by hand.
