Hubbell CS320LA Ac Toggle Switch 20A 277V 3-way

Product Description

The HUBBELL CS320LA is a specification-grade 3-way AC toggle switch designed for commercial electrical installations. Rated at 20 amperes and 120 to 277 volts AC, it handles single-pole and 3-way switching in lighting control circuits across a wide voltage range. The body is thermoplastic with an abuse-resistant nylon toggle in light almond finish. Internal contacts are silver alloy for reliable conductivity, and terminal screws are brass for solid, corrosion-resistant wire termination. A zinc-plated steel auto-grounding mounting bridge and brass green ground screw are included. Licensed electricians install this device in commercial branch circuits per NEC requirements.

The CS320LA is suited for commercial and specification-grade wiring projects where a 3-way switching configuration is required. It accepts 14 to 10 AWG copper stranded or solid conductors on side-wiring terminals, making it compatible with standard commercial conduit and cable wiring methods. The operating temperature range of -40 to 75 degrees C makes it appropriate for both climate-controlled interiors and unconditioned utility spaces. Light almond color coordinates with standard commercial cover plates sold separately.

Key Features

• 20A rating at 120 to 277V AC for wide-voltage commercial circuits
• 3-way operation for multi-location lighting control
• Silver alloy contacts for low-resistance, long-service switching
• Abuse-resistant nylon toggle resists mechanical damage in high-traffic areas
• Thread-cleaning captive mounting screw simplifies device replacement
• Zinc-plated steel auto-grounding mounting bridge reduces installation steps
• Accepts 14 to 10 AWG copper stranded or solid conductors on side terminals

Compatibility

Designed as an OEM-style specification-grade replacement or new-work 3-way toggle switch for commercial electrical systems requiring 20A 120 to 277V AC switching. Wall plate not included and must be ordered separately.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the branch circuit at the panelboard and verify absence of voltage before wiring. Side-wiring terminals accommodate 14 to 10 AWG copper conductors; do not use aluminum wire. Confirm the auto-grounding bridge makes secure contact with a metal device box where a grounding path through the box is intended.
