FAQs
The CSB120LA supports #14-10 AWG conductors with back and side wiring and a 14 lbf-in torque specification for the terminals. Start by de-energizing the panel, then prepare the conductors, secure them under the brass terminals with the screw connectors, and tighten to the recommended torque. Mount flush in the enclosure, verify the pole configuration is single-pole, and test with a low-voltage test sequence before full load energization.
Yes. The CSB120LA is rated 20A and 120/277V with a single-pole design and a broad load type support that includes incandescent, CFL, LED, as well as motor control and fan applications. This makes it well-suited for commercial lighting circuits and small motor loads in offices, retail, and similar settings, reducing the need for multiple switch types.
The CSB120LA carries cULus Listed and NOM certifications, along with Federal Specification Classification 6241 05. These marks validate safety performance, reliability, and regulatory compliance for commercial electrical installations in North American environments.
The switch features a flush-mount design with dimensions approximately 1.3 in depth, 4.2 in height, and 0.902 in width. It is color-matched light almond and uses brass terminals with screw connectors for secure wiring. Mounting is designed for flush installation in standard electrical boxes or panels, optimizing space in crowded enclosures.
Choosing the CSB120LA offers reliability and regulatory confidence with cULus and NOM certifications, reducing downtime and compliance risk. Its 20A rating, broad load compatibility, and back/side wiring streamline installation, lowering labor costs.
