Eaton HKD3175C - 175 A, 600 V, 3-Pole Circuit Breaker | AmpState

Engineered for dependable branch circuit protection, the Eaton HKD3175C delivers reliable overcurrent and short-circuit protection in panelboards and load centers. This 3-pole molded case circuit breaker is a purpose-built solution for demanding residential, commercial, and light industrial applications, offering peace of mind where uptime matters.

Why the HKD3175C stands out

• Compact molded case design maximizes panel space, making it easier to fit multiple protections in tight electrical enclosures without compromising safety or accessibility.
• Thermal-magnetic trip unit provides stable, repeatable protection performance. Thermal elements respond to sustained overcurrents, while magnetic trip offers immediate response to short circuits, reducing the risk of damage.
• 3-pole construction supports common three-phase configurations found in commercial and light industrial environments, simplifying wiring and trip coordination.
• OEM-ready compatibility is engineered for seamless integration with matching Eaton OEM load centers and panelboards, ensuring reliable operation and straightforward replacement or upgrades.
• 600V rating expands suitability to higher voltage applications, delivering robust protection for distribution circuits in commercial and industrial settings.

Ideal use cases

The HKD3175C is purpose-built for panelboards and load centers that require solid, long-term protection for high-current circuits. It’s well-suited for:

• Residential buildings with large electrical feeders and subpanels
• Small to midsize commercial spaces—offices, retail, and service environments
• Light industrial installations where reliable three-phase protection is essential
