Eaton CHB370 - 70 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton CHB370 is a rugged 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection for panelboards and load centers. With a 70-amp rating and a 240-volt operating range, it’s built to handle the demanding loads typical in residential, commercial, and light industrial settings.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing the risk of loosening and ensuring consistent performance in challenging environments.
• Thermal-magnetic trip unit delivers stable, repeatable protection across varying temperatures and load conditions, with fast magnetic response for short-circuit events.
• OEM-compatible design is crafted to integrate smoothly with matching Eaton OEM load centers and panelboards, simplifying replacement or upgrades without compatibility concerns.
• Versatile protection is suitable for branch circuit overcurrent and short-circuit protection, making it a reliable choice for a wide range of panel configurations.

Who benefits most: electricians, facility managers, and maintenance teams working on residential panels, commercial distribution boards, or light industrial distribution gear. The CHB370 is ideal when you need robust protection in panels that endure vibration, frequent cycling, or space-constrained installations where a dependable bolt-on solution is preferred over plug-on alternatives.

Use cases and scenarios:

• Upgrading or replacing aging breakers in existing Eaton panelboards and load centers to restore full protective performance.
• Installing new branch circuits in commercial or light industrial panels where vibration resistance and secure connections matter.
• Retrofitting panels in retrofit projects that require a precise, compatible 3-pole 70A 240V solution for balanced protection across phases.
