Eaton CH30B100R Main Breaker Loadcenter - UL 67
Part Number: CH30B100R
Quick Summary
The Eaton CH30B100R main breaker loadcenter is designed to deliver reliable power distribution for commercial and light-industrial applications. It combines a robust 100 A main breaker with 30 circuits in a compact 29.13 in L by 14.31 in W footprint, helping you optimize panel density and wiring routes. Field crews often contend with rain exposure and hub access; this unit addresses those challenges with rainproof tub hub plates and a sturdy metallic NEMA 3R enclosure. UL 67 and UL 50 listings reinforce safety and performance, while NEMA 3R supports outdoor or semi-outdoor locations. From a procurement perspective, the CH30B100R offers predictable lead times, a limited lifetime warranty, and copper bus for lower resistance and improved longevity, aligning with strict industry standards and maintenance planning.

Eaton Specification Sheet - CH30B100R
Eaton type CH circuit breaker limited warranty June 2024
The CH30B100R combines a 100 A main breaker with 30 spaces, enabling scalable distribution in a single enclosure and reducing the need for multiple panels, which lowers upfront costs and simplifies wiring routes. Copper bus minimizes resistance and voltage drop for improved efficiency and reliability in daily operations. The NEMA 3R metallic enclosure delivers weather resistance, expanding installation options to semi-outdoor or outdoor locations while maintaining safety and durability. Overhead feed with #6-1/0 AWG conductors ensures compatibility with common service feeders, reducing modification time during installation and enabling faster commissioning on new or upgrade projects. Tub hub closure plates provide rainproof hub protection and simplify field installation, while a single insulated/bondable neutral streamlines grounding practices and reduces wiring errors. The chassis also carries a limited lifetime warranty, reinforcing long-term value and serviceability for maintenance planning and ROI.
