Product FAQs
5 answersWhich panelboards accept the CHB290 circuit breaker?
This bolt-on breaker is specifically engineered for Cutler-Hammer Type PB and Type PH panelboards, along with compatible meter panels and multi-metering modules.
Are Eaton CH and CHB circuit breakers interchangeable?
No. While they share the same internal components and accessories, Type CH breakers are plug-on, whereas Type CHB breakers feature a specialized cradle for bolt-on installation in PB and PH panelboards.
Is the CHB290 suitable for HVAC applications?
Yes, the CHB series is HACR rated, meaning it is tested and approved for use with heating, air conditioning, and refrigeration equipment.
Do standard CH handle locks fit the CHB290?
Yes. Because the CHB breaker utilizes the standard CH frame within a bolt-on cradle, it accepts the same handle locks and accessories as standard CH plug-on breakers.
How does the trip mechanism operate on the 2-pole CHB290?
It utilizes a thermal-magnetic trip unit with an internal common trip connection. This ensures that an overcurrent or short circuit on either leg will simultaneously open both poles, disconnecting all ungrounded conductors.
