42-space, 42-circuit layout consolidates distribution into a single robust panel, reducing enclosure footprint while expanding capacity for complex control systems. Business impact: fewer cabinets, simpler wiring, and lower installed cost for multi‑load applications such as packaging lines and process controls. Application: industrial facilities seeking efficient, scalable power distribution. The copper bus provides low impedance connections, improving voltage stability under startup surges and heavy loads. Business impact: improved motor and drive performance, reduced energy losses, and longer component life. Application: high‑demand applications with motor loads and three‑phase equipment. NEMA 1 metallic enclosure delivers rugged indoor protection, supporting long service life in factory environments. Business impact: enhanced durability, lower maintenance, and easier inventory management. Application: indoor control panels in manufacturing settings. Top/bottom feed options offer wiring flexibility, simplifying installation and future upgrades. Business impact: faster commissioning and reduced field rework. Application: new builds and retrofit projects. The unit includes hub closure plates and is rated for three‑phase operation with a CC main circuit breaker, 200 A, and 10 kAIC interrupt rating. Business impact: safer fault handling and compliance with electrical protection standards. Application: critical process lines and machinery distributions. Warranty coverage is limited lifetime, providing long‑term protection against corrosion and component failure, which reduces lifecycle cost and downtime for facilities teams. Application: asset protection for industrial enclosures and electrical infrastructure.

FAQs

CH42B3200L is a CH‑type main breaker loadcenter designed for three‑phase distribution with top/bottom feed. It provides 42 spaces and copper bus in a NEMA 1 metallic enclosure. For installation, ensure correct mounting clearances, wire sizing up to #2/0 AWG-300 kcmil, and that hub closure plates are in place to maintain enclosure integrity and meet compliance.
Key specs include a 200 A main circuit breaker, 42 circuits and 42 spaces, three‑phase operation, copper bus material, 10 kAIC interrupt rating, NEMA 1 enclosure, and four conductors maximum. The unit is designed for indoor use with top/bottom feed, and is compatible with CH series main breakers for scalable expansion.
Yes. The CH42B3200L carries UL 67 enclosure standards and UL 50 component compatibility, ensuring safe operation in industrial environments. The NEMA 1 metallic enclosure further supports indoor protection. These certifications help meet regulatory requirements for control panels and reduce risk during audits and inspections.
The loadcenter offers a limited lifetime warranty and a robust build, which minimizes replacement cycles in demanding facilities. Its 42‑space design reduces panel count and simplifies spare part management. The copper bus improves efficiency, potentially lowering energy losses, and the included hub closure plates streamline installation and service continuity.
Choosing CH42B3200L provides long-term reliability, scalable capacity for growing lines, and easier maintenance due to clear specifications and robust construction. ROI benefits include reduced downtime from reliable fault protection (10 kAIC), faster commissioning with top/bottom feed flexibility, and single‑vendor compatibility within Eaton CH family for streamlined support and spare parts.
