Eaton HFD3035L - 35 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton HFD3035L—a 35 A, 600 V, 3-pole molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and loadcenters. With a compact profile and a thermal-magnetic trip unit, this breaker provides precise, repeatable protection for demanding residential, commercial, and light industrial applications.

Why this breaker stands out

• Compact molded-case design minimizes space usage in panelboards and loadcenters, helping you fit more circuits in a crowded electrical enclosure without sacrificing reliability.
• Thermal-magnetic trip unit delivers stable, repeatable protection by reacting to both sustained overcurrents and instantaneous short-circuit events, reducing nuisance trips and protecting downstream equipment.
• 3-pole configuration ideal for 3-phase circuits, common in commercial and light industrial environments, for balanced protection across all phases.
• OEM-compatible designed to be compatible with matching Eaton OEM loadcenters and panelboards, ensuring straightforward installation and dependable performance with your existing equipment.
• Versatile rating 35 A at 600 V makes it suitable for protective needs across a range of branch circuits, from lighting and HVAC controls to small motor loads in commercial settings.

How it protects your systems

The HFD3035L is engineered to provide fast, reliable interruption during fault conditions while minimizing disruption during normal operation. The thermal element responds to sustained overcurrent, while the magnetic mechanism handles instantaneous short circuits, delivering a protective response that helps shield wiring, devices, and downstream equipment.

Ideal applications

• Residential and small commercial panelboards requiring robust 3-phase protection
• Commercial lighting, power distribution, and control circuits in light industrial environments
• HVAC, pumps, and motor-control circuits where consistent, predictable tripping is essential
