Amperage and voltage compatibility directly translate to reduced wiring reworks and safer operation in commercial panels. The CSB320LA delivers 20A at 120/277V, enabling reliable control of lighting and auxiliary equipment with confidence in overcurrent protection and steady performance. Its back-and-side wiring option and screw terminals streamline field wiring, cutting installation time and labor costs while preserving a clean, corrosion-resistant connection. The switch’s three-way capability with a four-way wiring option supports multi-location control, reducing the need for additional devices in large enclosures and improving user ergonomics in commercial settings. Brass terminal enclosure and PVC body provide durable contact surfaces and weather-resistant performance in busy environments, while a light almond finish aids visibility in diverse panel layouts. Compact dimensions (1.3 in depth, 4.2 in height, 0.902 in width) enable easier retrofits and clearer labeling on crowded panels.

FAQs
CSB320LA supports both back- and side-wire termination using screw terminals designed for #14-10 AWG conductors. This enables flexible wiring layouts and reduces the need for adapters or remounting in crowded panels. For best results, land wires securely in the designated terminals and tighten to the specified torque to maintain low resistance and reliable operation.
The unit is rated for 20A and 120/277V with a single-pole configuration and three-way switch capability, plus a four-way wiring option. These specs support common commercial lighting and control circuits, delivering robust performance for variable voltages, while allowing flexible switching schemes in multi-location installations without compromising safety or reliability.
Yes. Designed for wall mounting with a compact footprint (1.3 in depth, 4.2 in height, 0.902 in width), CSB320LA fits in standard commercial enclosures. Its 20A, 120/277V rating covers typical lighting loads, and the screw terminals with brass enclosure offer dependable, long-lasting connections that simplify installation and reduce maintenance in busy facilities.
CSB320LA is cULus Listed and conforms to NOM Federal Specification Classification 6241 05, reflecting North American safety and performance standards. These certifications help ensure compliance for commercial installations, streamline procurement for regulated projects, and reduce qualification risk during audits and inspections.
The durable brass terminals and PVC construction minimize wear and corrosion, translating to longer service life and fewer replacement parts. Back-and-side wiring plus straightforward mounting reduce field labor and commissioning time, lowering total cost of ownership. In multi-location systems, flexible three-way and four-way configurations can lower device counts and simplify future upgrades.
