Leviton Mfg Co R50-0CSB4-2IS 4-way Switch 20A 120/277V

Product Description

The LEVITON MFG CO R50-0CSB4-2IS is a commercial-grade 4-way toggle switch rated for 20 amps at 120 to 277 volts AC. It is designed for use in multi-switch lighting control circuits where three or more switch locations control a single load. The ivory finish and back-and-side wiring options make it a versatile fit for commercial and institutional electrical installations. Licensed electricians install this switch as part of a 3-way and 4-way switching system in hallways, stairwells, large open-plan spaces, and similar applications requiring multiple points of control.

This switch is suited for commercial and light industrial environments where a higher 20-amp rating is required over standard 15-amp residential devices. The 120/277-volt rating covers both standard commercial branch circuits and 277-volt fluorescent lighting circuits common in office and warehouse settings. Back and side wiring accommodates both quick-wire and screw-terminal installation methods, supporting a range of wiring configurations and conduit or cable-wiring systems.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit at the breaker panel and verify the circuit is dead with a voltage tester before wiring. A 4-way switch must be wired in series between two 3-way switches in a multi-location circuit — do not install as a standalone switch. Secure all terminal screws firmly and confirm the device is properly grounded before restoring power.
