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

Product Description

The LEGRAND CS20AC1-LA is a 20-amp single-pole light switch rated for 120 to 277 volts AC. It is designed for commercial and residential lighting control applications where higher current capacity and wide voltage range compatibility are required. Electricians install this switch in standard wall-box configurations to control lighting circuits in office buildings, retail spaces, warehouses, and similar facilities. The 20-amp rating supports fluorescent, LED, and incandescent lighting loads typical in commercial installations.

This switch is suited for single-pole switching applications across a broad voltage range, making it appropriate for both standard 120-volt residential branch circuits and 277-volt commercial lighting circuits commonly found in commercial construction. It is a go-to specification for electrical contractors working on commercial tenant improvements, new construction, and lighting retrofit projects.
