Eaton HMCP003A0C - 3 A, 600 V, 3-Pole Circuit Breaker | AmpState

Engineered for dependable protection in compact spaces, the Eaton HMCP003A0C is a 3-pole molded case circuit breaker rated at 3 amperes and 600 volts. Built to guard branch circuits against overcurrent and short-circuit events, it fits seamlessly into panelboards and load centers, delivering reliable safety where space is at a premium.

• 3-pole, 3 A, 600 V configuration supports multi-wire or three-phase distribution while protecting critical circuits without oversizing your protections.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining gradual thermal response for overloads with fast magnetic action for short circuits, reducing nuisance trips and ensuring swift isolation when faults occur.
• Molded case, compact design maximizes panel space and simplifies installation in tight enclosures, helping you maintain clean labeling and organized wiring.
• OEM-loadcenter compatibility designed to be a drop-in fit with matching Eaton OEM panelboards and load centers, minimizing retrofit complexity and ensuring coordinated protection across the system.
• Versatile for multiple environments ideal for residential, commercial, and light industrial applications where small circuits require dependable protection and predictable performance.

Use cases and practical benefits:

• Protect dedicated lighting, receptacle, or control circuits in home subpanels or small office panels without overrating protection that could trip unnecessarily.
• Replace worn or aging breakers in OEM panelboards with a like-for-like Eaton solution to maintain protection coordination and reliability.
• Integrate into light commercial installations where compact breakers free up space for additional circuits and easier future expansion.
• Pair with compatible OEM panelboards in retrofit projects to preserve existing protection schemes while upgrading to a trusted, standardized component.
