Eaton QCR2040 - 40 A, 240 V, 2-Pole Circuit Breaker | AmpState

Meet the Eaton QCR2040 — a 40A, 240V, 2-pole molded case circuit breaker designed to deliver dependable branch-circuit protection in panelboards and load centers.

Engineered for reliability in residential, commercial, and light industrial settings, this unit uses a thermal-magnetic trip mechanism to provide stable, repeatable protection across a range of temperatures and load conditions. It detects overcurrent and short-circuit events quickly, helping to prevent wiring damage and equipment downtime.

• Compact molded-case design saves panel space and simplifies distribution layouts for tighter electrical panels.
• Thermal-magnetic trip unit delivers precise, repeatable tripping behavior for consistent protection in real-world conditions.
• 40A, 240V, 2-pole configuration is ideal for 240V circuits such as motors, HVAC equipment, and large appliances.
• OEM-friendly compatibility designed to fit matching Eaton panelboards and other OEM load centers that accept this style.
• Durable, space-efficient protection supports expansion and upgrades without adding bulky hardware.

Applications and use cases:

• Residential panels powering heat pumps, water heaters, and multi-wire branch circuits
• Commercial panels supporting lighting, receptacle banks, and small motor loads
• Light-industrial panels guarding equipment where reliable overcurrent and short-circuit protection is essential

Why this breaker stands out:

• Space-efficient design that helps maximize panel capacity without compromising protection.
• Consistent trip performance across varying load profiles, reducing nuisance trips and downtime.
• Trusted Eaton build quality and long history of reliable electrical protection.
