Key features that matter in real-world installs

• 40 amp current rating provides appropriate protection for heavy-duty 240 V loads such as water heaters, large air handlers, and other 240 V appliances.
• 2-pole design disconnects both hot legs simultaneously for enhanced safety and simpler panel wiring.
• 240 V operation tailored for standard residential and light commercial 240 V circuits.
• Part of Eaton’s reliable protection line, built to withstand field conditions and long service life.

Ideal use scenarios

Use this HQP2040H breaker when you need dependable protection on a 240 V branch circuit that draws up to 40 A. It’s well-suited for major appliances (water heaters, central AC components), dedicated circuits in workshops, or any 240 V equipment that requires robust overcurrent protection in a residential or light commercial panel.

Why choose the HQP2040H over generic breakers?

Because you’re protecting more than copper and plastics—you’re protecting circuits, equipment, and peace of mind. The HQP2040H is engineered to trip reliably under fault conditions, helping prevent fire risk and wiring damage, and it integrates smoothly into standard 2-pole 240 V panels without complex configuration.

Practical tips for installation and selection

• Verify that your panel is compatible with 2-pole, 240 V breakers and that the 40 A rating matches your circuit’s load calculation.
• Before servicing, shut off the main and follow proper electrical safety practices.
• Keep a spare HQP2040H on hand for quick replacement in ongoing panel maintenance.
