Product FAQs
6 answersWhich panelboards accept the CHB350 circuit breaker?
The CHB350 is designed specifically for Eaton and Cutler-Hammer Type PB and Type PH panelboards. It is also compatible with select meter panels and multi-metering modules that accept CHB series bolt-on breakers.
Will the CHB350 fit in a standard residential CH load center?
No. While it shares the CH family name, the CHB350 is a bolt-on breaker built for commercial Type PB and PH panelboards. Standard residential CH load centers require plug-on Type CH breakers.
How is the CHB350 installed into the panel?
This breaker utilizes a bolt-on mounting connection. It fastens directly to the panelboard bus, providing a secure mechanical and electrical connection for commercial and industrial applications.
Are Eaton and Cutler-Hammer CHB350 breakers interchangeable?
Yes. Eaton acquired Cutler-Hammer, and the CHB350 is the exact same component under both brand names. An Eaton CHB350 is a direct, manufacturer-approved replacement for an older Cutler-Hammer CHB350.
Is the CHB350 suitable for HVAC equipment?
Yes. The CHB350 is HACR rated, meaning it is tested and approved to safely protect dedicated heating, air conditioning, and refrigeration motor circuits.
What type of trip unit does the CHB350 use?
It is equipped with a fixed thermal-magnetic trip unit featuring Long-Time and Instantaneous (LI) functions. The thermal element handles mild overloads, while the magnetic element reacts immediately to severe short circuits.
