Eaton HFD3070 - 70 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton HFD3070, a 70 A, 600 V, 3-pole molded‑case circuit breaker built to deliver dependable branch circuit protection in panelboards and load centers.Designed for residential, commercial, and light industrial applications, this breaker combines compact form with precise protection to keep electrical systems safe and running smoothly.

Key advantages that set the HFD3070 apart

• Space‑efficient molded‑case design: Its compact footprint helps you maximize panel space without sacrificing protection.
• Thermal‑magnetic trip unit: A dual-stage system provides stable, repeatable protection—thermal sensing guards against nuisance overloads, while the magnetic element delivers instantaneous disconnect on high‑fault currents.
• Three‑pole configuration: Supports three‑phase circuits with common trip, delivering coordinated protection for multi‑wire loads and equipment banks.
• 70 A, 600 V rating: Suitable for mid‑sized branch circuits and equipment feeds in varied environments, backed by robust insulation and reliability.
• OEM panel compatibility: Designed to be compatible with matching OEM load centers and panelboards, helping preserve performance and installation consistency.

Why this matters for your projects

The HFD3070 isn’t just a breaker—it’s a protection solution that translates into real-world reliability. In busy commercial spaces, it maintains service for critical feeders while minimizing unexpected trips caused by transient faults. In light industrial settings, it guards motor and equipment circuits with a trusted trip profile that installers and maintenance teams rely on. And in residential contexts, it offers a durable, code‑compliant option for larger subpanels or service panels requiring 3‑pole protection.

Ideal use cases

• 3‑phase feeders in small offices, retail locations, or light manufacturing where compact protection is essential.
• Main or branch circuit protection for HVAC equipment, pumps, conveyors, and other three‑phase loads up to 70 A.
• Replacement in OEM panelboards where a 3‑pole, 70 A, 600 V molded‑case breaker is specified.
