Product FAQs
7 answersWhich panelboards accept the Eaton CHB250 circuit breaker?
The CHB250 is a bolt-on breaker specifically designed for installation in Cutler-Hammer Type PB panelboards, Type PH panelboards, and compatible meter panels.
What wire gauge is required for the CHB250 box lugs?
The terminal box lugs on this 50A breaker are designed to accept wire sizes ranging from 8 AWG to 4 AWG. Ensure your conductors are sized appropriately for the 50A load per NEC guidelines.
Can the CHB250 be used for HVAC equipment?
Yes, the CHB250 is HACR rated. It is approved for use with heating, air conditioning, and refrigeration equipment that requires a 50A, 2-pole breaker.
Does the CHB250 plug into the bus bar or bolt on?
This is a bolt-on circuit breaker. It requires a physical bolted connection to the panelboard bus, which provides a secure, vibration-resistant contact suitable for commercial applications.
How does the thermal-magnetic trip unit function on the CHB250?
The fixed thermal-magnetic mechanism provides dual protection. The thermal element offers a long-time delay to prevent nuisance tripping on temporary overloads, while the magnetic element provides instantaneous tripping during severe short circuits.
What does the 10kAIC rating on the CHB250 mean?
The 10kAIC rating indicates the breaker can safely interrupt up to 10,000 amps of fault current at 120/240V AC without sustaining damage, protecting the downstream circuit from severe short circuits.
Are Eaton BAB and CHB series breakers interchangeable?
No. Although both are miniature bolt-on breakers, they fit different panelboard designs. The CHB250 must be used in Type PB or PH panels, whereas BAB breakers are designed for other Cutler-Hammer panelboards.
