Legrand PS20AC1-BK 20A 120/277V Single Pole Switch

Product Description

The LEGRAND PS20AC1-BK is a single pole switch rated for 20 amps at 120 to 277 volts AC. It is designed for commercial and industrial lighting control applications where higher amperage switching is required. The black finish suits standard commercial wiring installations. Licensed electricians install this switch as a direct replacement or new-construction component in branch circuit lighting systems that operate at either standard 120-volt or high-voltage 277-volt supplies commonly found in commercial buildings.

This switch is suited for commercial lighting circuits in office buildings, warehouses, retail spaces, and similar occupancies where 277-volt fluorescent or LED lighting systems are standard. Its 20-amp rating accommodates higher-load lighting branch circuits beyond the capacity of a standard 15-amp device. The black color finish (BK designation) aligns with commercial device plate schemes.

Key Features

• 20-amp rating supports higher-load commercial lighting branch circuits
• Dual-voltage compatibility: 120 volts and 277 volts AC in a single device
• Single pole configuration for standard on/off lighting control
• Black finish suited to commercial wiring and device plate systems
• Designed for use in commercial and industrial electrical installations

Compatibility

Designed as an OEM-style single pole switch for commercial branch circuit lighting control systems operating at 120 or 277 volts AC.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the branch circuit at the panel and verify zero voltage with a meter before wiring. The switch must be installed in a listed electrical box appropriate for the wire fill and device type. Follow all local codes for commercial wiring methods and device mounting.
