Legrand CS20AC1-I Single Pole Switch 20A 120/277V

Product Description

The LEGRAND CS20AC1-I is a commercial-grade single-pole AC quiet switch rated for 20 amps at 120 to 277 volts AC. Designed for heavy-duty switching applications in commercial and industrial environments, this switch handles higher current loads than standard 15-amp residential devices. The ivory finish suits neutral-toned wallplate installations. Licensed electricians install this device as part of branch-circuit lighting or motor-control wiring in code-compliant electrical systems.

This switch is suited for commercial lighting circuits in office buildings, retail spaces, warehouses, and light industrial facilities where 20-amp branch circuits are required. The 120/277-volt dual-voltage rating makes it compatible with both standard residential-leg and commercial fluorescent-lighting circuits commonly wired at 277 volts. It is a single-pole configuration, controlling one circuit from one location.

Key Features

• 20-amp rating supports higher-load commercial branch circuits
• 120/277-volt dual-voltage AC rating covers both residential and commercial fluorescent lighting legs
• Single-pole configuration for single-location circuit control
• Quiet AC switch mechanism reduces audible switching noise
• Ivory finish for neutral-toned wallplate compatibility

Compatibility

Designed as an OEM-style replacement or direct installation switch for 20-amp single-pole commercial lighting and general-purpose branch circuits rated at 120 or 277 volts AC.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the branch circuit at the panelboard and verify absence of voltage with a meter before beginning work. Do not install on circuits exceeding the rated 20-amp or voltage limits. Torque all terminal screws to the value listed on the device or in the manufacturer documentation.
