Product FAQs
6 answersWhich panelboards are compatible with the Eaton CHB150 circuit breaker?
The CHB150 is designed to bolt into Cutler-Hammer Type PB and Type PH panelboards, as well as compatible meter panels.
How does the CHB150 connect to the panel busbar?
This breaker features a bolt-on connection, which provides a highly secure attachment to the panel busbar compared to standard plug-on residential breakers.
What wire sizes are accepted by the box lugs on the CHB150?
The box lug terminals on this 50A breaker accept copper or aluminum (Cu/Al) conductors ranging from 8 AWG to 4 AWG.
Is the CHB150 a Cutler-Hammer or Eaton breaker?
Eaton acquired Cutler-Hammer, so this breaker may be labeled under either the Eaton or Cutler-Hammer brand. Both are the exact same CHB series bolt-on breaker.
What type of trip mechanism does the CHB150 use?
It utilizes a thermal magnetic trip unit with fixed long-time and instantaneous (LI) trip functions to protect against overloads and short circuits.
Can I use a CHB150 in place of a standard CH plug-on breaker?
No. While they share similar electrical characteristics, CHB breakers are strictly bolt-on and are designed for commercial PB and PH panelboards. Standard CH breakers are plug-on and fit residential load centers.
