Eaton Specification Sheet - CH42B3200R
Eaton type CH circuit breaker limited warranty June 2024
200 A main breaker provides robust protection for mid-sized industrial or large commercial installations, reducing nuisance trips and improving uptime. This translates to lower maintenance costs and decreased unplanned downtime in manufacturing lines and data centers alike. The 42 circuits/spaces offer ample capacity for future wiring and branch circuit growth without requiring a full panel replacement, delivering a lower total cost of ownership over the asset’s life. Copper bus material ensures low resistance and stable voltage delivery under heavy load, improving motor startup performance and energy efficiency while reducing heat buildup in feeders. The NEMA 3R metallic enclosure is designed for outdoor or harsh environments, enabling outdoor installations or exposed wall mounting with weather-resistant protection. An interrupt rating of 10 kAIC provides reliable short-circuit protection for demanding workloads, supporting safer, high-uptime operations. The overhead feed and four-wire configuration simplify routing and grounding in modern electrical distributions, accelerating installation and reducing field wiring errors. With 42 spaces, 42 circuits, and hub closure plates furnished, the CH42B3200R reduces field modifications and accelerates project timelines while ensuring code-compliant, upgrade-ready performance. This loadcenter aligns with standard Eaton accessory ecosystems, allowing seamless compatibility with CH-series breakers and related distribution components for scalable panel design.
