No feed-thru lugs streamline field wiring, reducing installation time and minimizing wiring errors during panel configuration. This is particularly valuable in retrofit projects where space is restricted and routing can be complex. The main lug design supports clean feeder layouts, simplifies fault isolation, and speeds service updates, helping teams meet tight commissioning schedules in busy commercial or light-industrial facilities. 200 A capacity with 42 circuits and 42 spaces delivers scalable protection for medium-size electrical rooms without upsizing the enclosure. The BR 1-inch breaker compatibility supports modular, future-proof protection schemes, while the 208Y/120 and 240 V ratings accommodate common US feeder configurations. This aligns with engineering standards for offices, retail, and light manufacturing, reducing the need for premature panel upgrades. Aluminum bus material reduces weight during installation and improves thermal performance under high-load conditions. The robust, corrosion-resistant bus design supports conductor sizes up to #1 AWG-300 kcmil Cu/Al, enabling straightforward, code-compliant wiring for feeders and branch circuits. This combination enhances labor efficiency and long-term reliability in dense electrical rooms found in multi-tenant facilities. NEMA 1 metallic enclosure with surface mounting provides a durable indoor housing that protects components from dust and incidental contact, while enabling flexible layout in tight spaces. The included cover simplifies commissioning and ongoing maintenance, helping maintain enclosure integrity and compliance with site health and safety requirements in warehouses, offices, and processing areas. Compatibility with Type BR 1-inch breakers offers flexible procurement and future expansion without changing the panel framework. UL 67 and UL 50 certifications back performance and enclosure safety, and a 25 kAIC interrupt rating provides robust fault protection for moderate-load systems. The product carries a 10-year warranty, reflecting Eaton’s commitment to long service life and reduced lifecycle costs.

FAQs
This model supports surface mounting in indoor environments with a NEMA 1 metallic enclosure and a cover included. It is designed for 208Y/120 or 240 V systems and uses Type BR 1-inch breakers. Ensure cabinet clearance for 42 circuits and plan feeder routing to minimize cross-overs. The absence of feed-thru lugs reduces wiring complexity during retrofit projects.
The unit is specified for three-phase service with 208Y/120 and 240 V ratings, supporting 42 circuits within 42 spaces. Its aluminum bus and 200 A rating provide robust protection and capacity for mid-size commercial panels and light-industrial applications, while maintaining compatibility with BR 1-inch breakers for phased protection schemes.
UL 67 covers panelboards and associated equipment performance under normal and fault conditions, while UL 50 addresses enclosure integrity and protection against environmental factors. This loadcenter combines those certifications with a NEMA 1 metallic enclosure to ensure safe indoor use in typical commercial and light-industrial environments.
The 3BR4242L200S is designed for Type BR 1-inch breakers, offering straightforward procurement and future expansion within the same framework. It uses a main lug configuration without feed-thru lugs, so any later expansion should be planned within the 42-space constraint or via compatible retrofit panels that maintain the same form factor.
Eaton provides a 10-year warranty on this main lug loadcenter, reflecting confidence in long-term reliability. Regular inspections, clean environments, and prompt replacement of any worn components help maximize uptime. The included cover and robust NEMA 1 enclosure support ongoing protection against dust and incidental contact in busy facilities.
