Bryant 4903W 3-Way AC Toggle Switch, 20A 277V, Commercial Grade

The Bryant 4903W is a 3-way AC toggle switch rated 20A at 277V, engineered to control lighting fixtures and general-purpose electrical circuits from two separate switching locations, such as opposite ends of a hallway, stairwell, or large room. Built as a heavy-duty wiring device for commercial and industrial installations, the 4903W delivers dependable make-and-break switching action where consistent performance under higher electrical loads is required day after day. Its 20A, 277V AC rating makes it well suited for professional electrical systems that demand robust, code-compliant switching hardware capable of handling the higher-voltage branch circuits found in commercial buildings. As part of a 3-way circuit, the 4903W works alongside a second 3-way switch to provide flexible, convenient control of the same load from either location. This 3-way toggle switch platform is also offered as the Bryant 4903GLI and 4903I, sharing the same 20A, 277V AC switching performance across the model lineup while differing in actuator or lens configuration, so contractors can standardize on a single dependable switching platform across a job while selecting the exact model variant a given application calls for.

Key Features

  • 3-Way Configuration: Allows a single fixture or circuit to be switched on and off from two different locations, adding convenience and flexibility to lighting and circuit control.
  • AC Toggle Switch: Standard toggle-style actuator provides quick, familiar on/off operation for everyday commercial and industrial use.
  • Amperage Rating: Rated 20A, giving the switch the capacity to reliably handle higher electrical loads in demanding circuits without compromising performance.
  • Voltage Rating: Rated 277V AC, making it suitable for the higher-voltage branch circuits common in commercial and industrial power distribution systems.
  • Professional-Grade Build: Constructed as a durable, code-compliant wiring device intended for repeated daily use in demanding electrical environments.
  • Bryant Reliability: Backed by the Bryant name, a long-standing source of dependable wiring devices trusted by electrical professionals nationwide.
  • Model 4903W: Identified by Bryant model number 4903W for straightforward specification, ordering, and replacement, part of a shared platform with the 4903GLI and 4903I models.

Bryant 4903W – Frequently Asked Questions

1) Can a Bryant 4903 switch be used on a 277V lighting circuit?
Yes. The Bryant 4903 series toggle switch is rated 277V AC at 20A, which is the rating you need for the 277V branch circuits that feed fluorescent and LED lighting in commercial buildings. On a 120V circuit it works the same way; the 277V rating is the ceiling, not a requirement.
2) Do I need two 3-way switches to control a light from both ends of a hallway?
Yes. A 3-way switch like the Bryant 4903 has to be paired with a second 3-way switch, one at each location, to control the same fixture from either end of a hallway, stairwell or large room. A single 3-way on its own will not do multi-location control, and if you only need one control point you want a single-pole switch instead.
3) I only need to switch a light from one location, not two. What should I order instead of the Bryant 4903W?
The 4903W is a 3-way switch, wired in pairs to control one load from two locations. For single-location control use a single-pole device such as the Leviton 1221 SPST toggle switch, extra heavy-duty industrial specification grade, rated 20A at 120/277V, or the Leviton 1221-2KL, a 1-pole extra heavy-duty spec grade toggle at 20A 120/277V. Both hold the same 20A capacity as the 4903W.
4) What other brands make a 20A 277V three-way toggle switch I could substitute?
The closest cross-brand equivalent we carry is the Eaton Arrow Hart industrial grade three-way toggle, 20A, 120/277V. The Pass and Seymour CS20AC3I is a 20A specification grade commercial toggle in ivory, and the PS20AC3W is the industrial extra heavy duty spec grade version in white. Match the 3-way configuration when substituting, since a 1-pole device will not wire into a traveler circuit.
5) Is the Bryant 4903 heavy duty enough for a high traffic commercial building?
It is built as a heavy-duty commercial and industrial wiring device, intended for repeated daily switching on higher-load circuits rather than residential duty. For restrooms, corridors and back-of-house areas in schools, hospitals and hotels that is the class of device you want. If your spec calls out extra heavy-duty industrial grade by name, the Leviton 1201-2I is listed at that grade.
6) Are wall plates included with the Bryant 4903 toggle switch?
No. The 4903 is the switching device itself, a standard toggle-style wiring device. Wall plates are ordered separately, and on a 3-way job you need a plate at each of the two switch locations plus the second 3-way switch to complete the circuit.
7) What is the difference between the Bryant 4903W and the Leviton 1201-2I?
The Leviton 1201-2I is an extra heavy-duty industrial/specification grade toggle switch in ivory. The Bryant 4903W is a 3-way toggle switch rated 20A at 277V AC, wired with a second 3-way device to control one load from two locations. If your opening needs two-location control, the 3-way configuration of the 4903W is the deciding factor.
8) I need a switch that shows whether the load is on. Does the Bryant 4903W do that, or is there another option?
The Bryant 4903 platform is offered as the 4903W, 4903I and 4903GLI, which differ in actuator or lens configuration while sharing the 20A, 277V AC switching performance. If you specifically want a pilot light device, the Leviton 1201PLC is an industrial grade pilot light toggle switch, 1-pole, 120V - note it is single-pole and 120V, so it will not serve a 3-way 277V circuit the way the 4903W does.
9) Is the Pass & Seymour 660 Trademaster a substitute for the Bryant 4903W?
No. The Pass & Seymour 660 is a Trademaster grounding toggle switch, a different device family from the Bryant 4903W, which is a 3-way toggle rated 20A at 277V AC for two-location control. If you need multi-location switching on a 277V commercial branch circuit, look instead at a 3-way device such as the Eaton Arrow Hart AH-1223GY three-way toggle at 20A, 120/277V.
