Cooper Wiring Devices CSB420V 20A 4-way Toggle Switch

Product Description

The COOPER WIRING DEVICES CSB420V is a four-way toggle switch rated for commercial-grade applications in single-phase electrical systems. It operates across a voltage range of 120 to 277 VAC and is rated at 20 amps, making it suitable for higher-load lighting circuits beyond the capacity of standard residential switches. The toggle-style actuator provides a familiar, reliable switching action. This switch is designed for use in fluorescent lighting circuits and carries an ivory finish. It is installed by licensed electricians in commercial and light industrial settings where code-compliant, heavy-duty switching is required.

The CSB420V is a four-pole switch intended for multi-location control of lighting loads, particularly fluorescent fixtures, in commercial environments. Its wide voltage range of 120 to 277 VAC covers common single-phase commercial wiring configurations, including 277-volt fluorescent lighting circuits found in office buildings, warehouses, and retail spaces. The 20-amp rating meets the demand of higher-wattage fluorescent lighting banks. Its commercial-grade construction meets the durability and performance requirements of professional electrical installations.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify absence of voltage before wiring. Four-way switches are used between two three-way switches in multi-location switching configurations and must be wired accordingly. Do not exceed the 20-amp or 277 VAC ratings of this device.
