Product FAQs
6 answersWhat panelboards are compatible with the CHB325 circuit breaker?
The CHB325 is a bolt-on circuit breaker designed for use in Cutler-Hammer Type PB and Type PH panelboards, as well as compatible meter panels and multi-metering modules.
Can I use the CHB325 in a standard plug-on load center?
No. The CHB325 is a bolt-on circuit breaker designed specifically for bolt-on panelboards like the Type PB and PH. It cannot be installed in load centers that require plug-on Type CH breakers.
How much panel space does the CHB325 require?
The CHB325 is a 3-pole miniature circuit breaker that requires three spaces. Like other CH and CHB series breakers, it measures 0.75 inches wide per pole, taking up 2.25 inches of total width in the panelboard.
What wire sizes are accepted by the box lugs on the CHB325?
The terminal box lugs on this 25-amp breaker accept copper or aluminum wire ranging from 14 AWG to 8 AWG.
How do I reset a tripped CHB325 circuit breaker?
When a CHB series breaker trips, the handle moves to a center position between ON and OFF. To reset it, you must first push the handle to the full OFF position, then push it back to the ON position to restore power.
What type of trip mechanism does the CHB325 use?
This breaker features a fixed thermal-magnetic trip unit. It uses a bimetal element for inverse-time delayed tripping on mild overloads and a magnetic armature for instantaneous tripping during severe short circuits.
