Cooper Wiring Devices AH1221B 20A Toggle Wall Switch

Product Description

The COOPER WIRING DEVICES AH1221B is a single-pole, industrial-grade toggle wall switch rated for 20 amps and 120 to 277 VAC single-phase operation. Designed for demanding commercial and industrial environments, it handles fluorescent lighting loads across a wide voltage range without a dimming function. The switch carries an operating temperature range of -4 to 140 degrees F, making it suitable for installations where ambient conditions vary. Licensed electricians install this device as a standard line-voltage switching solution where durability and code compliance are required.

This switch is built for commercial, industrial, and institutional applications where a heavy-duty, non-dimming toggle control is needed. It handles fluorescent lamp circuits and other resistive or inductive 20-amp loads. The wide 120 to 277 VAC rating accommodates both standard residential voltage and the higher single-phase voltages common in commercial panel configurations. Its brown finish suits industrial enclosures and brown-device wiring schemes.

Key Features

• Wide voltage range: 120 to 277 VAC single-phase, covering standard and commercial circuit voltages
• Non-dimming toggle operation suitable for fluorescent and other non-dimmable loads
• Operating temperature range of -4 to 140 degrees F for varied ambient conditions
• Meets ANSI C-73, UL 20 (File E18704), and UL 94 standards
• Single-pole configuration for straightforward on/off switching at one location

Compatibility

Designed as an OEM-style industrial replacement toggle switch for single-pole, 20-amp, 120 to 277 VAC wall-switch applications in commercial and industrial wiring systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the circuit at the breaker panel and verify absence of voltage with a meter before beginning work. The single-pole configuration requires correct identification of line and load conductors prior to termination. Do not use this switch on dimming circuits or with loads exceeding the 20-amp rating.
