Eaton CHB115 - 15 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

The Eaton CHB115 is a 15A, 120V, 1-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built for reliability in residential, commercial, and light industrial environments, this device combines sturdy mounting with precise protective timing to keep sensitive electrical systems safe and uptime high. Available through AmpState, the CHB115 is a practical upgrade or replacement part for Eaton panelboards and OEM load centers.

Key benefits

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing the risk of loose contacts and arcing in environments with movement or equipment vibration.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding to both overcurrent and short-circuit conditions, helping prevent nuisance trips while guarding circuits against damage.
• OEM-compatible design is engineered to pair with matching Eaton panelboards and load centers, ensuring a clean fit and reliable performance without aftermarket guesswork.
• Versatile application suitable for residential wiring upgrades, commercial panel servicing, and light industrial circuits that demand dependable protection in compact form.

Ideal use cases

Use the CHB115 to protect individual branch circuits within electrical panelboards and load centers where a 15-ampere load is typical—think lighting circuits, receptacle circuits in living spaces, small HVAC controls, and auxiliary equipment in light commercial settings. The bolt-on design simplifies installation in retrofit or service upgrade projects, providing a secure connection that withstands vibration and temperature cycling common in basements, mechanical rooms, or equipment closets.

Why this matters

Choosing a molded case circuit breaker with a thermal-magnetic trip means you’re balancing protection speed with reliability. The CHB115 reacts quickly to short circuits to minimize damage, yet avoids unnecessary trips on normal inrush or transient surges thanks to its well-calibrated magnetic and thermal responses. When paired with Eaton’s compatible panelboards, it ensures coordinated protection across the entire system, supporting easier maintenance and safer operation over the life of the installation.

Practical tips for installation and use

• Ensure you’re installing into an Eaton-compatible panelboard or load center to maintain coordinated protection and warranty expectations.
• Verify torque requirements for bolt-on mounting to achieve the intended vibration resistance and bus connection integrity.
• Use as part of a targeted protection strategy for dedicated circuits where 15A rating aligns with expected load profiles and wiring sizes.
• Replace only with the same part number or compatible Eaton CHB family equivalents to preserve protective characteristics.
