FAQs
To install the 3BR3042LC200, verify indoor dry location, ensure supply and distribution conductors are sized per #1/0 AWG to 300 kcmil Cu/Al, and mount using the G1 enclosure with the included cover. Connect feeders to the 200 A lugs, align with Type BR 1-inch breakers, and commission per UL 67 UL 50 guidelines. Ensure grounding requirements are met and label circuits for future expansion to meet NEC standards.
Key specs include a 200 A amperage rating, 42 circuits across 30 spaces, three-phase 208Y/120 and 240 V operation, copper bus material, 25 kAIC interrupt rating, and NEMA 1 metallic enclosure. It is designed for four-wire systems and supports Type BR 1-inch breakers, enabling reliable fault clearing and scalable distribution in mid-size facilities.
Yes, for indoor dry environments where a robust main lug distribution is required. The unit uses a metallic NEMA 1 enclosure that provides durable protection, UL 67 and UL 50 certifications ensure compliance with electrical code expectations, and its 25 kAIC rating helps withstand short-circuit events common in manufacturing settings. For harsher environments, consider additional enclosure protection or indoor-rated variants.
The 3BR3042LC200 carries UL 67 and UL 50 certifications, reflecting compliance for low-voltage distribution equipment and enclosure integrity. The NEMA 1 enclosure rating indicates protection for indoor dry locations. These certifications support safe operation in control rooms, mechanical spaces, and light industrial facilities while simplifying regulatory approvals and inspections.
The unit’s 10-year warranty, durable copper bus, and solid short-circuit rating contribute to lower maintenance and replacement costs over its lifespan. Compatibility with BR 1-inch breakers reduces spare parts diversity, while the combination mounting and include-cover design speed up commissioning. Overall, facilities realize lower downtime, predictable performance, and extended service life in routine power distribution tasks.
