FAQs
The 34242DYSN is designed around the BR series design and accommodates standard 3‑phase, 208Y/120 and 240 V configurations. For exact breaker compatibility and accessory kits, refer to Eaton’s specification sheet (Eaton BR product family) and the current product notes, which detail mounting allowances, enclosure clearances, and approved accessory ranges.
Yes. The catalog notes indicate approval for 150 A and up residential services in New York City. When planning a NYC upgrade, verify service requirements, permit scope, and ensure the panel configuration supports the feeder and load profile for 208Y/120 or 240 V three-phase systems as applicable.
Surface mounting simplifies both new installations and retrofits by attaching directly to a wall without a recessed cavity. The unit ships with a cover and a door lock for security, and its 42‑space layout enables clean, scalable wiring paths. This reduces field modification time and accelerates commissioning in industrial or commercial applications.
The enclosure is galvanized steel with a NEMA 1 rating, suitable for indoor use and basic protection against dust and incidental moisture. It carries UL 50 and UL 67 certifications, ensuring cabinet integrity and electrical safety under typical service conditions. This combination supports regulatory compliance and reliable operation in commercial environments.
Eaton backs the BR main lug loadcenter with a 10-year warranty, reflecting long-term durability. Documentation such as the specification sheet and warranty guide provide installation tips, lifecycle guidance, and steps for field service or product issues, helping sustain uptime and return on investment for critical electrical infrastructure.
