Eaton HMCP025D0Y - 25 A, 600 V, 3-Pole Circuit Breaker | AmpState

Eaton HMCP025D0Y is a 25A, 600V, 3-pole molded case circuit breaker engineered for dependable branch circuit protection in panelboards and load centers. With a compact molded case design and a thermal-magnetic trip unit, it delivers stable, repeatable performance across varying loads and environments, making it a trusted choice for both upgrades and new installations.

Key benefits that matter in real-world panels

• Space-efficient design: The compact molded case construction helps you maximize panel layout and fit more circuits into smaller spaces without compromising protection.
• Thermal-magnetic trip unit: Combines thermal protection for overloads with magnetic protection for sudden short circuits, ensuring fast, predictable disconnection under fault conditions.
• Three-pole protection: Handles 3-phase circuits with a single device, simplifying wiring, coordination, and downstream protection in commercial and light industrial projects.
• OEM-ready compatibility: Specifically designed to be compatible with matching Eaton OEM load centers and panelboards for seamless substitutions and reliable performance.
• Reliable ratings: 25A nominal current, 600V maximum voltage—appropriate for a wide range of panelboard configurations and medium-voltage distributions in eligible applications.

Applications and use cases

• Residential, commercial, and light industrial panels that require robust branch circuit overcurrent and short-circuit protection.
• Panelboard and loadcenter upgrades where space is at a premium and a proven thermal-magnetic solution is preferred.
• New installations that demand a compact breaker compatible with OEM ecosystems, ensuring straightforward installs and maintenance.
• Three-phase feeders in systems where reliable tripping speed and coordination with other protective devices are essential.

Why this breaker stands out from typical options

Unlike generic breakers, the HMCP025D0Y combines a purpose-built molded case design with a precisely engineered thermal-magnetic trip unit, delivering consistent trip performance across ambient conditions. Its three-pole configuration simplifies protection for 3-phase circuits, while its OEM compatibility reduces installation friction and lifecycle maintenance. This makes it especially well-suited for panel upgrades in existing facilities or new builds where space constraints and reliable protection are priorities.
