Eaton QCR2035 - 35 A, 240 V, 2-Pole Circuit Breaker | AmpState

The Eaton QCR2035 is a 2-pole molded case circuit breaker rated at 35A and 240V, engineered to protect your branch circuits with precision in panelboards and load centers. With the part number QCR2035, it’s easy to source a compatible, OEM-replacement option that fits seamlessly into Eaton-compatible systems.

Why the QCR2035 stands out

• Compact molded-case design helps you maximize panel space without compromising protection, making it an ideal choice for tighter electrical enclosures in both homes and small commercial installations.
• Thermal-magnetic trip unit delivers stable, repeatable protection. The thermal element responds to gradual overcurrent, while the magnetic element provides a fast, decisive response to short-circuit events—reducing the risk of damage to wiring and connected equipment.
• Two-pole configuration ensures simultaneous interruption of both conductors on a 240V circuit, enhancing safety and reliability for dual-leg loads.
• OEM compatibility is built-in—designed to pair with matching Eaton panelboards and load centers, helping to maintain correct trip curves and coordinated protection across your system.
• Versatile applications suitable for residential, commercial, and light industrial circuits that require robust 240V, 2-pole protection.

Ideal applications and use cases

Use the QCR2035 to safeguard any 240V branch circuit within Eaton-compatible panelboards and load centers. It’s well suited for spaces where space efficiency matters, such as compact electrical panels in residential basements, small offices, or light commercial spaces. Typical scenarios include protecting HVAC feeders, water heating circuits, and other 240V equipment that benefits from reliable power interruption during fault conditions.

What this means for you

• : The combination of thermal and magnetic trip mechanisms provides predictable response, helping prevent electrical fires and equipment damage due to overcurrent or short circuits.
