CHB220 - 20Amp Circuit Breaker

CHB220 - 20Amp Circuit Breaker

The Eaton CHB220 is a 20 Amp, two-pole breaker made for Eaton’s CH Loadcenters. It’s the kind of breaker you reach for when you’re replacing an existing CH unit and need everything to line up the same—same fit, same rating, same connection style—so the panel stays consistent and nothing needs to be modified.

You’ll see it in everyday residential panels and light commercial setups, especially on dedicated circuits where you can’t split protection between legs.

The CHB220 uses a plug-in design, so it snaps right into compatible Eaton CH Loadcenters. If you’re swapping out an existing CH breaker, it’s usually a straightforward job—pull the old one, seat the new one, and you’re back in service without any adjustments to the panel. Inside, it has a thermal magnetic trip system, which handles the two main things you’d expect: slower overload conditions and sudden short circuits. It reacts based on electrical demand, helping protect the circuit within its rated limits.

With support for #14–8 AWG wire, it fits the typical branch circuit wiring found in many installed CH systems. The two-pole setup makes it a common choice for 240V loads or any circuit where both conductors need to disconnect at the same time.

Overall, the CHB220 is best thought of as a direct replacement breaker for existing Eaton CH panels. It’s not about changing anything—it’s about keeping the system working the way it was originally designed, with the same form and function.
