Eaton CS320LA Toggle Switch - cULus Listed
Part Number: CS320LA
Quick Summary
Toggle switch performance for commercial wiring is ideal for wall-mounted control in 120/277V commercial environments. Owners and engineers often struggle with durability, proper termination, and compliance in busy installations. This CS320LA model delivers cULus listed, NOM, and Federal Specification 6241 05 certifications, plus three-way wiring for flexible control. By combining durable copper alloy terminals with wall-mount installation and side-wire compatibility, it supports faster, compliant deployments. Engineers appreciate the device's compatibility with #14-10 AWG conductors and its copper alloy terminals for reliable terminations. In practice, the three-way operation and side-wire wiring simplify installations and maintenance in high-traffic commercial settings. This combination translates to faster project completion, lower field rework, and more consistent performance across shifts.

Electrical rating and configurations enable reliable load control in commercial panels. The CS320LA supports 20A at 120/277V with single-pole and three-way operation, delivering flexible control for lighting, fans, and small equipment across offices, retail spaces, and light-industrial facilities. This versatility reduces device counts, streamlines wiring, and improves commissioning speed, which translates into faster project turnover and lower installation costs on large-scale commercial builds. Wiring method and terminals simplify field connections and minimize errors. Side-wire wiring with screw terminals provides secure terminations, while the 0.031 inch terminals and copper alloy contacts resist corrosion and wear in high-traffic applications. This combination reduces callback requests, extends service life, and enhances reliability when toggling between multi-location controls during busy shifts. Durable materials and compact form support long service life in demanding environments. PVC construction, light almond finish, and a rugged mounting arrangement ensure the device remains visually compatible with interiors while standing up to daily use. Engineers gain predictable performance metrics, particularly in commercial lighting control and power switching, helping to meet maintenance windows and minimize unplanned downtime. Compliance and certifications provide clear regulatory alignment. The CS320LA is cULus Listed, NOM compliant, and carries Federal Specification Classification 6241 05, strengthening pass/fail outcomes during inspections and reducing risk of non-conformance in building permits. Three-way operation further enables flexible control strategies without sacrificing safety or traceability. Installation compatibility and physical dimensions support easier retrofits and new installs. Weighing only 0.12 lb with a compact footprint (1.3 in depth, 4.2 in height, 0.902 in width), the device fits tight wall boxes and commercial panels, with straightforward side-wire connections and screw terminals that installers trust for repeatable results across shifts and teams.
