Eaton QBHW1020 - 20 A, 240 V, 1-Pole Bolt-On Circuit Breaker | AmpState

The Eaton QBHW1020 is a 20A, 240V, 1-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built for environments where vibration is a factor, this breaker provides a secure connection and predictable protection performance across residential, commercial, and light industrial electrical systems.

• Secure bolt-on mounting ensures a rigid, vibration-resistant bus connection, helping maintain continuity and reducing loosening of connections in demanding applications.
• Thermal-magnetic trip unit delivers stable, repeatable protection—quick response to short circuits while minimizing nuisance trips from normal load fluctuations.
• OEM-compatible design aligns with matching OEM loadcenters and panelboards for seamless replacements, upgrades, or new installations without compatibility concerns.
• 1-pole, 240V configuration is ideal for single-circuit protection of 20A loads, including lighting, outlets, appliances, and small machinery in residential and light commercial settings.
• Versatile across settings suitable for panelboards and loadcenters used in homes, offices, and small-scale industrial environments.

Ideal use cases

• Replacing a failed breaker in existing Eaton or OEM-compatible panelboards where bolt-on mounting is required.
• Installing in circuits that demand reliable protection for lighting, outlets, and small equipment with a 20A rating.
• Enhancing panel reliability in vibration-prone areas such as basements, utility rooms, or equipment spaces, where a secure bus connection matters.

Why it stands out

Compared with other mounting styles, the bolt-on design of the QBHW1020 provides a sturdier, long-lasting connection that resists loosening in environments with vibration or thermal cycling. The thermal-magnetic protection ensures fast, dependable response to short circuits while smoothly handling continuous overloads, offering safer operation and reduced service interruptions.
