Eaton CHB220 - 20 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The Eaton CHB220 is a rugged 20A, 240V, 2-pole bolt-on molded case circuit breaker designed for reliable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. Built to stay secure in demanding environments, this breaker delivers dependable protection where it matters most — at the point of power distribution.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, helping to prevent loose contacts and nuisance trips in panel installations subject to vibration or movement.
• Thermal-magnetic trip unit delivers stable, repeatable protection by automatically responding to overloads and short circuits, ensuring quick, precise disconnections when needed.
• 2-pole, 240V configuration handles common 240V circuits with a single device, simplifying wiring and protection for multi-wire branch circuits.
• 20A rating makes it ideal for typical residential, commercial, and light industrial loads such as HVAC, large appliances, and circuit-fed equipment
• OEM-compatible design ensures seamless compatibility with matching Eaton OEM load centers and panelboards, reducing compatibility concerns during upgrades or service work.

The CHB220 responds precisely where it matters—protecting wiring, devices, and people by interrupting fault currents quickly while maintaining steady performance under normal operation. The thermal-magnetic mechanism provides dependable response to both sustained overloads and sudden short circuits, delivering protection that you can count on throughout the life of the panel.

Ideal use scenarios

• Upgrading or replacing breakers in residential service panels and load centers that require bolt-on protection with solid bus connections
• Protection for 240V branch circuits in light commercial environments, including HVAC feeders, water heating circuits, and large appliance runs
• Panelboard maintenance in retrofit projects where OEM compatibility and voltage specifications match the CHB220

Why this bolt-on solution stands out — in contrast to plug-in options, the bolt-on design emphasizes connection integrity in environments where vibration or movement is a concern. The CHB220 combines a robust, molded-case construction with a compact footprint, enabling reliable long-term protection without compromising space in crowded panels.
