Description
Features
- This subpanel is specifically engineered for 3-phase, 3-wire or 4-wire configurations operating at 208Y/120V or 240V AC. It allows for balanced power distribution across commercial branch circuits, making it the perfect solution for dedicated light industrial machinery or specific HVAC equipment feeds.
- The QO403L100S is designed as a fixed main lug only load center rated for 100 Amps. This configuration passes upstream main breaker protection directly to downstream branch circuits, allowing you to bypass the expense of an unnecessary secondary main breaker in subpanel installations.
- It features 3 single-pole spaces allowing for up to 3 circuits, with zero tandem breaker compatibility to maintain strict code compliance. This compact footprint is purposely built for space-restricted utility closets where you need to isolate a small number of dedicated 3-phase loads without wasting wall space.
- This premium Square D panel utilizes a high-conductivity, tin-plated copper busbar shield. The protective tin plating prevents copper oxidation and corrosion over time, guaranteeing a low-resistance electrical connection that runs cooler and minimizes long-term commercial maintenance callouts.
- This heavy-duty load center boasts an industrial-grade 65 kA short circuit breaking rating to safely handle sudden, high-amplitude fault currents. This massive threshold ensures your installation easily satisfies stringent Canadian electrical code requirements near high-capacity utility transformers.
- This product is fully CSA certified and cULus listed, arriving ready with a surface cover and a rugged NEMA 1 indoor rating. Constructed from welded sheet steel with a baked enamel grey finish, it resists scratching and environmental wear during rough-ins, delivering a clean setup that passes electrical inspections with flying colors.
