Eaton QCHW3020H - 20 A, 240 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton QCHW3020H—a 20A, 240V, 3-pole molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Its compact design maximizes panel space without sacrificing protection, making it an ideal upgrade for crowded electrical enclosures.

Key features that matter in real-world installs

• 20A at 240V—safeguards common branch circuits such as HVAC, pumps, motors, and lighting feeders, delivering reliable protection where it counts.
• 3-pole configuration—ensures simultaneous disconnection of all poles on three‑phase or multi-wire circuits for enhanced safety and code compliance.
• Molded case design—offers a compact footprint that frees up precious panel space, while maintaining rugged durability for long-term use in residential, commercial, and light industrial settings.
• Thermal-magnetic trip unit—provides stable, repeatable protection: the thermal element handles gradual overloads, and the magnetic element delivers fast response to short circuits, reducing downtime and panel wear.
• OEM-compatible—designed to work with matching Eaton OEM load centers and panelboards, ensuring smooth replacement and reliable performance without retrofit headaches.

Why this breaker is a smart choice

• Space-efficient protection—maximize available panel space in new builds or upgrades, especially where every inch of enclosure matters.
• Consistent protection across temp and load conditions—the thermal-magnetic trip mechanism maintains predictable responses, reducing nuisance trips in environments with temperature fluctuations or varying load profiles.
• Clear alignment with your installation—explicitly designed for residential, commercial, and light industrial applications, making it a versatile option for electricians stocking a single, reliable solution for multiple projects.

Use cases and practical scenarios

• Replacing a failed 3-pole 20A breaker in a three‑phase or multi‑wire panel within a small office building.
• Upgrading a crowded residential service panel where space is at a premium but reliable 240V protection is required for motor loads and heat pumps.
• Installing in light commercial spaces to protect branch circuits feeding compressors, pumps, or other 240V equipment with a compact, OEM-compatible unit.
