Product FAQs
6 answersCan I install the CHB280 in a standard Eaton CH loadcenter?
No. The CHB280 is a bolt-on circuit breaker designed for commercial panelboards, such as Type PB and Type PH panels. Standard CH loadcenters require plug-on breakers.
What types of panelboards are compatible with the CHB280 breaker?
This bolt-on breaker is engineered for use in Cutler-Hammer Type PB and Type PH panelboards, as well as compatible meter panels and multi-metering modules.
What wire sizes are accepted by the terminals on the CHB280?
The box lugs on this 80-amp breaker accept wire gauges ranging from 4 AWG up to 1/0 AWG. Ensure the wire is properly sized for the load and that the lugs are torqued to the manufacturer specifications during installation.
How does the CHB280 connect to the panelboard bus?
The CHB280 features a bolt-on connection type. It must be securely bolted directly to the bus bars of a compatible panelboard, which provides a robust mechanical and electrical connection for commercial applications.
Is the Eaton CHB280 the same as the Cutler-Hammer CHB280?
Yes. Eaton acquired Cutler-Hammer, and they continue to manufacture this breaker under the Eaton Cutler-Hammer brand. The CHB280 catalog number remains the same and is a direct replacement for older Cutler-Hammer or Westinghouse versions with the identical part number.
Does the CHB280 provide ground fault or arc fault protection?
No. The CHB280 is a standard thermal-magnetic circuit breaker providing long-time and instantaneous (LI) trip functions for overload and short-circuit protection. It does not include GFCI or AFCI capabilities.
