Bryant BRY-CSB315B-S – Frequently Asked Questions

1) Can the Bryant CSB315B switch be used on a 277V commercial lighting circuit?
Yes. The CSB315B is rated 15A at 120/277V, so it works on both standard 120V residential circuits and 277V commercial lighting branch circuits. That dual rating is why the same part number gets used in offices and in houses without swapping catalogs.
2) What do I need on the other end to make a Bryant CSB315B 3-way switch work?
A 3-way switch never works alone. The CSB315B controls one load from two locations, so it needs a companion 3-way switch at the second location on the same circuit, plus a pair of travelers run between them. If you need control from three or more locations, you keep the two 3-ways at the ends and put a 4-way in between.
3) Is there a 4-way version of the Bryant CSB switch for three-location control?
Yes, the CSB420BW is the 4-way, 20A, white device in the same family. Wire it between the two 3-way switches on the travelers to add a third control point. The 3-way models are CSB315B (15A brown), CSB315BI (ivory), CSB315BW (white), CSB320B (20A brown), CSB320BI and CSB320BW.
4) Should I order the 15A or the 20A Bryant CSB 3-way switch?
Match the switch to the branch circuit breaker. On a 15A lighting circuit the CSB315B is the right call; on a 20A circuit, step up to the CSB320B. Both are 3-way and both are offered in brown, ivory and white. The 20A device is also what most commercial specs call for on general-purpose 20A lighting runs.
5) What is the closest equivalent to a Bryant CSB315B 15A 3-way toggle switch from another brand?
The Pass & Seymour CS15AC3W is the nearest match: a commercial specification grade toggle switch in white, which lines up with the Bryant CSB315BW 15A 3-way in white. Pass & Seymour also lists the CS15AC3I in ivory, matching the Bryant CSB315BI ivory version. Both keep the same toggle actuator style as the Bryant rather than switching to a paddle.
6) I need a 3-way switch with a decorator paddle instead of a toggle - what should I order?
The Bryant CSB315B series is a toggle-style 3-way device. For a paddle actuator on the same kind of circuit, the Pass & Seymour 2623W is a specification grade 3-way decorator paddle switch rated 20A at 120V/277V in white - the same dual 120/277V rating the Bryant series carries, in a decorator form factor. Note it is a 20A device, so compare it to the Bryant CSB320BW rather than the 15A CSB315BW.
7) I need to control the same lights from three locations - is the CSB315B the right device?
No, a 3-way device like the CSB315B pairs with one companion 3-way to give two control points. For three or more locations you add a 4-way in the middle of the travelers: the Bryant CSB420BW is a 20A 4-way in white, used together with 3-way switches at each end of the run.
8) What colors does the Bryant CSB 3-way switch come in, and will it match my existing devices?
Three device colors: brown (CSB315B / CSB320B), ivory (CSB315BI / CSB320BI) and white (CSB315BW / CSB320BW). For a property manager standardizing a building, pick the color already in the wall plates and order the whole floor in one part number. The 4-way CSB420BW is white only.
9) Is the Bryant CSB315B a toggle switch or a decorator paddle?
It's a standard toggle-style 3-way switch, so it takes a conventional toggle wall plate, not a decorator/Decora opening. If you want a paddle instead, the Pass and Seymour 2623W is a 3-way decorator paddle switch rated 20A at 120/277V in white.
10) Can I use a Bryant CSB315B as a regular on/off single-pole switch?
No. A 3-way device has no marked ON/OFF positions and uses a common terminal with two travelers, so it isn't a substitute for a single-pole switch in a standard one-location circuit. Order a single-pole device for that opening and keep the CSB315B for two-location control.
11) Is the Pass & Seymour TradeMaster TM switch a substitute for the Bryant CSB315B?
Not directly. The Pass & Seymour TM TradeMaster is a 15A decorator switch, so the amperage aligns with the Bryant CSB315B but the actuator is a decorator paddle rather than the Bryant's toggle, and the TradeMaster line is a general-purpose grade rather than the commercial specification grade family. If you want a toggle in 15A, the Pass & Seymour CS15AC3W commercial specification grade toggle is the closer cross.
12) Will a Bussmann TPHCS-250 work in place of a Bryant CSB315B wall switch?
No. The Bussmann TPHCS-250 is a TPH series high-current switch rated 80 Vdc with a 100kA short-circuit current rating - a DC power disconnect device, not a wall-box lighting control. The Bryant CSB315B is a 15A 120/277V AC 3-way toggle switch that mounts in a standard device box for multi-location lighting. They are not interchangeable in either direction.
13) If the load needs a 20A switch instead of 15A, what are my options?
Within the Bryant line, step up to the CSB320B in brown, CSB320BI in ivory, or CSB320BW in white for a 20A 3-way, and CSB420BW for a 20A 4-way in white. On the Pass & Seymour side, the 2623W is a 20A 120V/277V specification grade 3-way in white with a decorator paddle actuator.
14) Is the Bryant CSB315B suitable for hallway and stairwell lighting in a commercial building?
That's its main use. Hallways, stairwells and rooms with more than one entry are exactly where you need to kill a light from either end, and the 15A 120/277V rating covers both house-power and commercial lighting panels feeding those runs.
