Eaton CHP30B100R Main Breaker Loadcenter - NEMA 3R
Part Number: CHP30B100R
Quick Summary
The Eaton CHP30B100R main breaker loadcenter is designed to safely distribute power in commercial and light industrial panels. Engineers often struggle with balancing weather resistance, space constraints, and serviceability in service equipment. UL 50 and UL 67 listings, plus a NEMA 3R metallic enclosure, provide reliability for indoor and outdoor use. Coupled with a 100 A main and copper bus, it delivers scalable service in commercial buildings while reducing installation time and wiring complexity. This makes it ideal for quick commissioning, easier maintenance, and consistent compliance with enclosure standards. For facility managers, the combination of service equipment compatibility and a 60-circuit capacity translates to a lower total cost of ownership.

FAQs
Install the CHP30B100R in its NEMA 3R metallic enclosure, connect the overhead feed to the main CH breaker, mount the 30-space panel, and wire the 60 circuits using copper bus. Include the cover and hub closure plates for rainproof hubs. Verify grounding and compliance with UL 50/UL 67 requirements during commissioning.
Yes. It uses the CH main breaker configuration and supports 100 A rated operation, single-phase 120/240 V, overhead feed, copper bus, 60 circuits across 30 spaces, and a 29 in depth enclosure. The unit is UL listed (UL 50/UL 67) and designed for service equipment where applicable.
Ideal for commercial and light industrial service entrances, outdoor or damp locations, and installations requiring rainproof hubs. Its 60‑circuit capacity and NEMA 3R enclosure make it suitable for exterior panel assemblies, retrofit projects, and spaces where main protection and reliable service equipment are critical.
The CHP30B100R is UL listed under UL 50 and UL 67 with a NEMA 3R metallic enclosure. It also carries a limited lifetime warranty, offering long-term protection against material and workmanship defects, which supports maintenance planning and lifecycle cost stability.
The copper bus reduces resistance losses and thermal stress, improving reliability and reducing hot-spot risks. The enclosure’s weather protection lowers outdoor UI exposure, while the included cover and rainproof hubs speed installation. Together with UL certifications and a warranty, these factors translate to lower maintenance interventions and a faster return on investment.
