Leviton Telcom M1221-I Toggle Switch Single Pole 20A

Product Description

The LEVITON TELCOM M1221-I is a single-pole toggle switch built on the Lev-Lok platform, rated for 20 amps at 120/277 volts. It is designed for commercial and industrial electrical installations where a secure, locking-style device is required. The ivory finish matches standard commercial wallplate configurations. Licensed electricians install this switch as part of branch-circuit wiring in lighting and general-load applications. The Lev-Lok mounting system provides a more secure device-to-wallplate connection than standard snap-in designs, reducing the risk of accidental removal in high-traffic or institutional environments.

This switch suits commercial, institutional, and light industrial environments where standard 20-amp single-pole switching is required. Typical applications include office lighting circuits, corridor controls, and utility spaces wired to 120-volt or 277-volt branch circuits. The 277-volt rating makes it compatible with fluorescent and LED commercial lighting systems commonly fed from 480Y/277-volt panelboards. It is sold as a single unit and is appropriate for new construction and retrofit installations.

Key Features

• 20-amp rating supports heavy-duty branch-circuit loads
• Dual voltage rating at 120 and 277 volts covers both residential-style and commercial lighting circuits
• Lev-Lok platform provides a secure device-to-wallplate connection
• Single-pole configuration for standard on/off switching of a single circuit leg
• Ivory finish for compatibility with commercial wallplates and device covers

Compatibility

Designed as an OEM-style replacement or new-installation single-pole toggle switch for commercial and industrial branch-circuit applications requiring a 20-amp, 120/277-volt Lev-Lok device.

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 with a non-contact voltage tester before any wiring work. Ensure the box fill calculation accounts for the device and all conductors per NEC Article 314. Do not exceed the 20-amp or voltage ratings marked on the device.
