Bryant 4 Series Single-Pole Locking AC Switch, 20A 277V

The Bryant 4 Series Locking AC Switch line delivers secure, tamper-resistant control of AC-powered circuits in commercial and industrial environments, and this listing covers the 4802L, 4901L, and 4902L models within that family. Each is a single-pole (SP) locking switch rated 20A at 277V, engineered to provide a dependable on/off control point wherever equipment, lighting, or process circuits require switching that can be secured against accidental or unauthorized operation. As part of Bryant's broader 4 Series locking device platform, these switches are built for electricians and facility teams who need a straightforward switching point that can be locked down in occupied commercial spaces, back-of-house equipment rooms, and industrial work areas.

Bryant 4901L – Frequently Asked Questions

1) What's the difference between the Bryant 4802L, 4901L and 4902L locking switches?
They differ by pole configuration and amperage. The 4802L is double-pole 15A, the 4901L is single-pole 20A, and the 4902L is double-pole 20A. All three are locking AC switches in Bryant's 4 Series. Pick single-pole for simple on/off of one hot leg, and double-pole when you need to break both legs of a 277V or 208/240V circuit, which is the usual choice for equipment disconnect duty.
2) Is the Bryant 4802L locking switch rated for 20 amps?
No. The 4802L is the 15A double-pole version. If you need 20A, order the 4901L for single-pole or the 4902L for double-pole. Getting this wrong on a 20A branch circuit means an undersized device.
3) Is the Pass & Seymour 2623W a substitute for a Bryant 4 Series locking AC switch on a 277V lighting circuit?
Both carry a 277V rating - the Bryant 4 Series locking AC switches are rated 20A 277V, and the Pass & Seymour 2623W is a specification grade decorator paddle switch rated 20A 120V/277V. The difference is function and actuation: the 2623W is a 3-way paddle switch, while the Bryant devices are single-pole and double-pole locking switches whose actuator is designed to be secured against operation. If the circuit is switched from two locations, the 3-way 2623W does what a single-pole Bryant cannot; if the point needs to be locked out against unauthorized switching, the Bryant 4 Series is the device that does it.
4) For a high-current DC disconnect, is a Bryant 4 Series locking switch the right device?
No. The Bryant 4 Series locking AC switches are AC devices rated 20A at 277V. For DC switching at high fault levels, the Bussmann TPHCS-250 is a TPH Series high-current switch rated 80 Vdc with a 100kA SCCR - a different class of device for DC power and high short-circuit duty. Use the Bryant 4 Series for AC lighting and equipment control circuits, and the TPH Series switch where the circuit is DC.
5) What does the L in Bryant 4802L mean?
The L denotes the locking mechanism. The 4 Series locking AC switches have an integrated locking design so the switch can be secured against accidental or unauthorized operation, which is why facility teams use them in equipment rooms and occupied commercial spaces rather than a standard toggle.
6) Do I need a locking switch or will a standard commercial toggle do?
Use a locking switch only where the switch position has to be protected: mechanical equipment, process circuits, or lighting that must not be flipped by an occupant. For ordinary wall switching, a standard spec grade device is the simpler buy, such as the Pass & Seymour CS15AC3W commercial specification grade toggle, or the CS15AC3I in ivory. Neither of those locks; the Bryant 4 Series does.
7) I need three-way switching at 277V, not a locking switch. What should I use instead?
The Bryant 4 Series locking switch is a single-pole or double-pole device, so it won't do three-way control from two locations. For that, the Pass & Seymour 2623W specification grade decorator paddle switch is a 3-way rated 20A at 120V/277V in white.
8) What is a simpler standard toggle switch to use where a locking switch is not required?
The Pass & Seymour CS15AC3W is a commercial specification grade toggle switch in white, and the CS15AC3I is the same commercial specification grade switch in ivory. Either is a conventional toggle with no locking actuator, so anyone can operate it. Choose the Bryant 4 Series when the control point has to be secured; choose the CS15AC3 toggles when open operation by occupants or staff is intended and you want a matching white or ivory device in the wall plate.
9) Can I use a Pass & Seymour TradeMaster switch in place of a Bryant 4802L or 4902L?
The Pass & Seymour TM TradeMaster is a 15A decorator switch. The Bryant 4 Series covers a 15A double-pole device as the 4802L and 20A devices as the 4901L single-pole and 4902L double-pole, all rated 277V. So the TradeMaster does not cover the 20A 4901L or 4902L on amperage, and it is a single-pole style decorator device rather than a double-pole locking switch, which rules it out where both legs of the circuit are switched or where the switch must be locked.
10) Can these Bryant locking switches be used as a motor or equipment on/off control in an industrial panel?
Yes, that's a stated application. The 4 Series locking AC switches are used in commercial and industrial control panels, equipment and machinery power control circuits, and lighting circuit switching. For breaking both legs of the supply, choose one of the double-pole models, the 4802L at 15A or the 4902L at 20A.
11) If I need a white or ivory finished switch to match other devices in the room, what are my options?
The Bryant 4 Series locking AC switches are specified by pole configuration and amperage - 15A double-pole, 20A single-pole, and 20A double-pole at 277V. Where a color-matched device face is the deciding factor, the Pass & Seymour CS15AC3W is offered in white and the CS15AC3I in ivory, both commercial specification grade toggle switches, and the 2623W is a white specification grade decorator paddle. Those are the choices when appearance in an occupied space matters more than a lockable actuator.
12) Where can I get full Bryant switch specifications for the 4 Series?
Bryant publishes the 4 Series locking switch data in its Wiring Devices Catalog Section E (Switches), and the device also appears in the Bryant Full Line Catalog. Both are available as PDFs from ZenSupply for submittal packages and spec verification.
