Product FAQs
7 answersCan I use the CHB220 in a standard Eaton CH load center?
No. The CHB220 is a bolt-on circuit breaker designed specifically for Type PB and PH panelboards, meter panels, and multi-metering modules. Standard residential CH load centers require plug-on Type CH breakers, not bolt-on Type CHB breakers.
Is the Eaton CHB220 the same as the Cutler-Hammer CHB220?
Yes. Eaton acquired Cutler-Hammer and continues to manufacture the CHB series. The Eaton CHB220 is the exact, UL-listed replacement for older Cutler-Hammer CHB220 breakers installed in legacy PB and PH panelboards.
What is the difference between the CHB220 and the CH220?
The CHB220 features a bolt-on connection for commercial panelboards and metering modules. The CH220 features a plug-on connection for standard residential load centers. Because of the different mounting styles, they are not interchangeable.
How does the CHB220 mount to the panel bus?
The CHB220 uses a bolt-on connection type. It secures directly to the panelboard bus using a threaded fastener, providing a highly reliable mechanical and electrical connection suitable for commercial applications and metering modules.
How should the wiring be terminated on the CHB220?
The breaker is equipped with box lugs that accept 14 AWG to 8 AWG wire. When installing, strip the insulation according to the manufacturer guidelines and torque the terminal screws to the exact value specified on the side of the breaker to ensure a secure connection.
Is the CHB220 suitable for straight 240V applications?
Yes. Because it is rated for 120/240VAC, this 2-pole breaker can safely supply straight 240V loads or 120/240V multi-wire branch circuits. Ensure the system fault current does not exceed the 10kAIC interrupting rating at 240V.
How does the thermal-magnetic trip mechanism in the CHB220 operate?
The breaker uses a Long-Time and Instantaneous (LI) trip function. The thermal component provides a delayed trip to prevent overheating from sustained overloads, while the magnetic component trips instantaneously to clear severe short circuits.
