Eaton QC3015H - 15 A, 240 V Circuit Breaker | AmpState

The Eaton QC3015H is a 15A, 240V molded case circuit breaker engineered to guard branch circuits against overcurrent and short circuits within panelboards and load centers. Its compact molded-case design makes efficient use of limited panel space, while the thermal-magnetic trip unit delivers stable, repeatable protection across a range of operating conditions. Designed for compatibility with matching OEM Eaton loadcenters and panelboards, this breaker is a reliable choice for a variety of applications in homes, businesses, and light industrial settings.

What makes the QC3015H stand out

• Space-efficient design maximizes panel capacity in tight installations without compromising protection.
• Thermal-magnetic trip unit provides precise overcurrent and short-circuit protection, reducing nuisance trips and delivering predictable response when faults occur.
• OEM-compatible with Eaton panelboards and loadcenters ensures seamless integration, labeling, and performance without retrofits.
• Clear 15A, 240V rating targets typical 240V branch circuits, delivering safe and reliable protection for connected devices and conductors.
• Durable, proven construction built to withstand routine panel maintenance and steady operating conditions in residential, commercial, and light industrial environments.

Ideal use cases

• Residential panelboards safeguarding circuits that operate at 240V or feed 120/240V loads through multiwire configurations.
• Commercial panel installations protecting small equipment, receptacle banks, and lighting circuits in compact spaces.
• Light industrial panels where dependable backup protection is needed without bulkier equipment.

How it protects your system

When current exceeds the 15A rating or a short-circuit develops, the QC3015H’s thermal-magnetic mechanism trips the circuit to interrupt power, preventing wiring damage, overheating, and potential fire hazards. The combination of thermal (overload) and magnetic (short-circuit) protection delivers

• Faster disconnection during high-current faults
• More predictable trip behavior under varying temperatures
• Consistent performance aligned with compatible Eaton panel systems

Installation and compatibility tips

• Pair with Eaton OEM loadcenters and panelboards for optimal fit, labeling, and coordinated performance.
• Verify the panel’s space and mounting provisions match the molded case design to ensure secure seating and reliable electrical contact.
• Use as a direct replacement or in new installations that require a like-for-like 15A, 240V protection device to maintain code-compliant branch circuits.
• Label the circuit clearly to reflect its protected load and alignment with the panelboard’s safety plan.
