Feature → Business Impact → Application: Main lug design without feed-thru lugs reduces potential fault paths and simplifies wiring, speeding up installation and future expansion in new builds or retrofit projects. This directly lowers commissioning time and minimizes retrofit costs in commercial facilities that demand reliable power distribution. Feature → Business Impact → Application: 200 A rating with 42 circuits/spaces supports high-density distribution for mid-size industrial panels and large commercial spaces, enabling scalable power layouts without adding separate enclosures. Use this in warehouses or data centers where space is at a premium. Feature → Business Impact → Application: Aluminum bus and metallic enclosure offer corrosion resistance and lighter weight with robust mechanical strength, improving ease of handling during installation and reducing transport and labor costs for outdoor installations. Feature → Business Impact → Application: NEMA 3R enclosure with a cover included provides weather protection and straightforward outdoor deployment, suitable for roofed loading docks and exterior equipment rooms, while maintaining code-compliant safety. Feature → Business Impact → Application: 25 kAIC interrupt rating, UL 50/UL 67 certifications, and a 10-year warranty deliver long-term safety, compliance, and total cost of ownership reductions, particularly attractive for OEMs and service providers managing multiple sites. Feature → Business Impact → Application: Type BR 1-inch breakers compatibility and support for 208Y/120 and 240 V systems simplify procurement and stocking for distributors, helping standardize assemblies across projects and improve spare parts availability.

FAQs
The 3BR4242L200R is a main lug loadcenter designed for three-phase systems and is compatible with BR 1-inch breakers. It supports 208Y/120 and 240 V configurations, up to 42 circuits, and uses an aluminum bus in a NEMA 3R enclosure, simplifying integration into existing 3-phase distributions.
Its NEMA 3R metallic enclosure provides weather resistance for outdoor installations, while UL 50 and UL 67 certifications underpin safe operation in industrial settings. A cover is included to protect terminations, and the unit is built to withstand typical outdoor environmental conditions without compromising performance.
The loadcenter features a 25 kAIC interrupt rating and is configured as a main lug unit with no feed-through lugs, which simplifies the topology and reduces potential fault paths while delivering strong short-circuit protection for the downstream circuits.
This model carries UL 50 and UL 67 certifications, confirming safety and performance for power distribution equipment. It also comes with a 10-year warranty, providing long-term support and helping justify total cost of ownership in maintenance-intensive facilities.
With a robust 200 A rating, 42 circuits, and durable aluminum bus, maintenance requirements are minimal while reliability remains high. The compatibility with BR 1-inch breakers simplifies spare parts stocking, reducing downtime during breaker replacements and upgrades, contributing to faster project ROI and lower lifecycle costs.
