Cooper Wiring Devices CSB315B Toggle Three Way Switch

Product Description

The COOPER WIRING DEVICES CSB315B is a three-pole, three-way toggle switch rated for commercial-grade electrical installations. It operates at 15 amps across a voltage range of 120 to 277 volts AC, single phase, making it suitable for a wide range of lighting control applications. The switch carries a brown finish and is designed for fluorescent lighting circuits. Its operating temperature range spans -4 to 140 degrees F, supporting use in both indoor and light industrial environments. Licensed electricians install this switch as part of branch circuit wiring where three-way switching control is required.

This switch is intended for commercial electrical applications requiring reliable toggle-operated three-way control. It is commonly installed in hallways, stairwells, and multi-point lighting circuits in commercial buildings. The 120 to 277 volt rating makes it compatible with both standard and high-voltage single-phase fluorescent lighting branch circuits. Its commercial grade construction supports higher-cycle and higher-demand environments compared to residential-grade devices.

Compatibility

Designed as a commercial-grade three-way toggle switch for use in single-phase fluorescent lighting branch circuits operating at 120 to 277 volts AC.

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 handling wiring or mounting the device. The switch is a three-pole device and must be wired correctly at both switching locations to ensure proper three-way operation. Use appropriately rated wire connectors and follow the device markings for terminal identification.
