Eaton HFD3070L - 70 A, 600 V, 3-Pole Circuit Breaker | AmpState

Introducing the Eaton HFD3070L — a 70 A, 600 V, 3-pole molded case circuit breaker designed for dependable branch circuit protection in panelboards and loadcenters. Available through AmpState, this unit brings trusted Eaton protection to residential, commercial, and light industrial applications while fitting seamlessly into existing Eaton panel ecosystems.

Engineered for consistent performance, its thermal-magnetic trip unit delivers stable, repeatable protection across a range of loads, helping prevent nuisance trips and safeguarding wiring and equipment from overcurrent and short-circuit conditions.

Why this breaker stands out

• Space-efficient molded case design: A compact footprint that maximizes panel space, making it easier to fit additional circuits or modernize panels without increasing enclosure size.
• Thermal-magnetic trip for reliable protection: The thermal element responds to gradual overcurrent, while the magnetic element responds to short circuits with fast, predictable disconnection.
• OEM-compatible integration: Precisely matched to Eaton OEM loadcenters and panelboards for a clean fit and coordinated trip across all poles.
• Three-pole configuration for three-phase systems: Common-trip operation across hot legs simplifies protection in commercial and light industrial environments up to 600 V.
• Versatile across settings: Ideal for a range of installations where space, reliability, and coordinated protection matter.

Practical applications and scenarios

Use the HFD3070L to protect branch circuits in new installations, panel upgrades, or service panels that require a three-pole, 600 V device. It’s well-suited for three-phase feeders, motor circuits in small industrial layouts, and distribution within commercial panels, delivering predictable protection with a straightforward replacement path within Eaton’s ecosystem.
