Eaton QC2020 - 20 A, 240 V, 2-Pole Circuit Breaker | AmpState

The Eaton QC2020 is a 20A, 240V, 2-pole molded case circuit breaker built to deliver dependable branch circuit protection in panelboards and loadcenters. Its compact design maximizes panel space while maintaining robust protection for everyday electrical demands.

Why choose the Eaton QC2020? This device combines a thermal-magnetic trip unit with a streamlined molded-case form factor to provide stable, repeatable protection against both overloads and short circuits. The two-pole construction ensures simultaneous disconnection of both hot legs on 240V circuits, safeguarding equipment and reducing the risk of dangerous imbalances.

• Compact molded-case design optimizes panel space, letting you fit more circuits in the same enclosure.
• Thermal-magnetic trip delivers precise overload protection with fast response to short-circuit events, minimizing nuisance trips and equipment damage.
• 2-pole, 240V operation provides coordinated protection for all 240V branch circuits.
• 20A rating tailored for common residential, commercial, and light industrial loads.
• OEM compatibility designed to drop into matching Eaton panelboards and loadcenters for straightforward replacements and upgrades.
• Versatile applications suitable for homes, small offices, retail spaces, and light industrial environments needing reliable circuit protection.

What problems does it solve? The QC2020 delivers clear, predictable protection when circuits draw more than their rated current or when faults create a short circuit. The thermal element handles gradual overloads, while the magnetic element trips quickly on high-energy faults, helping prevent overheating, fire risk, and equipment failure.

Ideal use cases include installing in residential main panels to protect lighting and receptacle circuits, in small commercial panels for office lighting and electronics, and in light industrial setups where compact, dependable protection is essential for fixtures, pumps, or control circuits. When you need a reliable, field-compatibile replacement that preserves panel organization and protects critical loads, the Eaton QC2020 is a trusted choice.
