Leviton CS120-2I – Frequently Asked Questions

1) Can the Leviton CS120 toggle switch be used on a 277V lighting circuit?
Yes. The Leviton CS120 AC quiet toggle switch carries a 120/277V AC rating, so it works on both standard 120V branch circuits and the 277V lighting circuits common in commercial buildings fed from a 480/277V system. It's rated 20 amps on either voltage.
2) I need three-way switching at this opening instead of single pole - what should I order?
The Leviton CS120 is a 1-pole device, so it only controls a load from one location. For two switch locations on the same circuit, the Eaton Arrow Hart AH-1223GY is an industrial grade three-way toggle switch rated 20A at 120/277V, or the Pass & Seymour CS20AC3I family covers commercial 20A specification grade toggles. Match the voltage and amperage you already have on the circuit.
3) What is the closest equivalent to the Leviton CS120 20A toggle switch from another manufacturer?
The Pass & Seymour CS20AC3I is the nearest match: a commercial 20A specification grade toggle switch in ivory. The Leviton CS120 is also a specification grade device rated 20A at 120/277V, single pole, and is offered in brown and ivory. If you are standardizing on ivory devices across a floor, either will match the wallplate scheme; the Leviton brown option has no counterpart in the Pass & Seymour part named here.
4) Can I use a Bryant 4801W in place of the Leviton CS120?
Not on the same circuit rating. The Bryant 4801W is a single-pole 15A 277V AC toggle switch in white, while the Leviton CS120 is rated 20A at 120/277V. If the branch circuit is a 20A lighting circuit, the 20A device is the one to install. The Bryant is also white, so it will not match a brown or ivory device run.
5) What colors does the Leviton CS120 AC quiet switch come in?
Two: Brown (CS120-2) and Ivory (CS120-2I). Both are the same 20A, 120/277V single-pole device, so you can mix them across a building and keep one part number family while matching existing wallplate colors.
6) Is a 20A switch overkill for a 15A lighting circuit?
No, it's the normal spec-grade choice. A 20A rated switch can be used on a 15A or 20A circuit, and the heavier contact rating is why specification grade devices hold up under constant commercial switching. The CS120 is rated 20A at 120/277V and is graded Specification.
7) What's the difference between a specification grade switch and a residential grade toggle?
Specification grade devices like the Leviton CS120 use heavier contacts and stronger straps for repeated daily switching in commercial buildings, where a residential grade device is built for light duty. In the comparable range, Pass & Seymour's TradeMaster line (660G in brown, 663LAG in light almond) is the general-purpose grounding toggle, while their CS20AC3I is the 20A commercial specification grade equivalent to the CS120.
8) Which Leviton part number do I order for the brown AC quiet switch?
Brown is CS120-2. Ivory is CS120-2I. Both are 1-pole, 20A, 120/277V AC quiet toggles.
9) Will the Leviton CS120 fit a standard toggle wallplate and existing device box?
Yes. It's a standard toggle-style wiring device, so it mounts to a normal single-gang strap opening and takes any standard toggle wallplate, including multi-gang plates when ganged with other toggles. Brown and Ivory versions are both standard toggle openings.
10) What is the difference between the Leviton CS120 and the Pass & Seymour PS20AC3W?
Both are specification grade 20A toggle switches. The PS20AC3W is an industrial extra heavy duty specification grade device in white; the Leviton CS120 is a commercial/specification grade AC quiet toggle, 120/277V, 1-pole, offered in brown and ivory. Choose on color scheme and on whether the job spec calls for the extra heavy duty industrial line.
11) My existing devices are light almond - is there a toggle switch to match instead of the Leviton CS120?
The Leviton CS120 is offered in brown and ivory only. For a light almond device run, the Pass & Seymour 663LAG TradeMaster grounding toggle switch is a light almond thermoplastic toggle. Confirm the amperage on the circuit before you set the fleet standard, since the CS120 is the 20A specification grade option.
12) What is an AC quiet toggle switch and where does it matter?
It's a toggle switch whose mechanism dampens the snap sound when thrown. Leviton's CS120 is built for that quiet action, which is the reason it gets specified in offices, patient areas, hotel rooms and any occupied space where switch noise is noticed. Function is the same on/off control as any single-pole toggle.
