Eaton QBCAF1020 - 20 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Eaton QBCAF1020 is a 20 Amp, 120-volt, 1-pole bolt-on molded case circuit breaker designed for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters.

Built to handle everyday panel vibrations, its secure bolt-on mounting creates a rigid bus connection, reducing the risk of loose contacts that can lead to overheating or intermittent trips. The thermal-magnetic trip unit delivers stable, repeatable protection by combining a thermal overload response with a fast magnetic trip for short circuits, ensuring quick, predictable action when it matters most.

Why this breaker stands out

• Bolt-on mounting: secure, vibration-resistant fit in compatible panelboards and loadcenters, promoting long-term contact integrity.
• Thermal-magnetic protection: coordinated thermal and magnetic trip technology provides reliable protection across typical residential and light commercial loads.
• OEM compatibility: designed to work with matching OEM loadcenters and panelboards for straightforward replacement and wiring consistency.
• Versatile application: ideal for residential, commercial, and light industrial circuits that require a 20A, 120V single-pole breaker.
