Industrial Locking Switch for Secure Circuits
The Bryant 4803L is a 2-pole maintained barrel key locking switch built for industrial environments. Its stainless steel finish and high-performance copper alloy movable contact arm support reliable operation in demanding settings. The maintained action keeps the circuit in the selected position until the key is turned again. This switch suits facilities that require authorised access to electrical controls.
Rated for 15 Amps Across 120 to 277 Volts AC
The device carries a 15 A rating at 120 to 277 V AC and a horsepower rating of 1/2 to 2 HP. Back and side wiring methods give installers flexibility during connection. UL, CSA and NOM standards compliance confirms the switch meets recognised safety benchmarks. No antimicrobial coating is applied to the stainless steel surface.
Fits Standard Industrial Wall Boxes
Back and side wiring terminals accommodate common installation practices without special tools. The barrel key locking mechanism prevents unauthorised toggling while allowing approved personnel to operate the switch normally. The maintained function eliminates the need for spring-return momentary alternatives in lighting or motor circuits. Buyers who need a momentary action or a non-locking toggle should consider other switch types.

Questions about this item
How is the Bryant 4803L wired and which step do installers often miss?
Connect the 15 A, 120 to 277 V circuit to both back and side terminals; the step often missed is tightening the side screws after the back-wire clamps seat.
What part of the Bryant 4803L will need replacement after extended industrial use?
The high-performance copper-alloy movable contact arm wears first; plan to replace the switch when the maintained action feels loose or contact resistance rises.
What operational limit appears first when the Bryant 4803L runs continuously at full load?
The 15 A, 120 to 277 V rating and 1/2 to 2 HP motor limit define the thermal boundary; sustained operation at those values will hit temperature rise before any other constraint.
