Eaton HKD3250C - 250 A, 600 V, 3-Pole Circuit Breaker | AmpState

When you need reliable, space-efficient protection for power distribution, the Eaton HKD3250C delivers. This 250 A, 600 V, 3-pole molded case circuit breaker is engineered to guard panelboards and loadcenters against overcurrent and short circuits. Built to fit seamlessly in Eaton systems and compatible OEM panels, it’s a robust solution for demanding electrical environments.

Key benefits that actually matter

• Compact molded-case design: A slim profile that maximizes panel space and helps you fit more circuits in a single enclosure.
• Thermal-magnetic trip unit: Combines heat-overload sensing with an instantaneous magnetic trip to deliver stable, repeatable protection every time a fault occurs.
• Three-pole protection: 3-pole construction ensures synchronized disconnection across all three phases in 3-phase systems, reducing unbalanced faults and protecting equipment.
• OEM-compatible: Designed to integrate with matching Eaton loadcenters and panelboards for straightforward installation and predictable performance.
• Versatile across applications: Suitable for residential, commercial, and light industrial environments where dependable overcurrent and short-circuit protection matters.

Where it shines: ideal use cases

• New panel installations in homes or small-to-mid-size commercial settings requiring robust 3-phase protection.
• Retrofits and upgrades in existing Eaton systems or OEM panels that require a 250 A, 600 V, 3-pole breaker.
• Distribution panels for HVAC equipment, lighting circuits, pumps, and other heavy-load applications where reliable short-circuit protection is essential.

How it protects your system

The HKD3250C leverages a two-tier trip mechanism:

• The thermal portion responds to sustained overloads by heating a bimetal strip, delivering precise, repeatable protection against overheating.
• The magnetic portion provides instantaneous tripping during a short circuit, interrupting fault current before damage spreads.
• After a fault clears, the breaker can be reset, restoring normal operation without replacing the device.
