Eaton HMCP250W5Y - 250 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Eaton HMCP250W5Y is a 250A, 600V, 3-pole molded case circuit breaker engineered to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Its compact design helps maximize valuable panel space while delivering robust protection for 3-phase electrical systems in residential, commercial, and light industrial environments.

• Compact molded case design provides efficient use of panel space, making it easier to fit into tighter electrical enclosures without sacrificing protection capabilities.
• Thermal-magnetic trip unit offers stable, repeatable protection performance—responding quickly to short circuits with a magnetic trip and calmly handling overloads via the thermal element.
• 3-pole configuration ideal for three-phase systems, providing coordinated protection across all phases and simplifying safe shutdown of multi-wire circuits.
• 600V rating suited for commercial and light industrial applications, enabling reliable protection for higher voltage branch circuits.
• 250A continuous rating designed to guard large feeders and equipment against overcurrent events without nuisance trips in normal operation.
• OEM-compatible fit engineered to be compatible with matching Eaton OEM load centers and panelboards, ensuring proper mounting, electrical continuity, and streamlined installations.

This device is an excellent choice for electricians, electrical contractors, and panel builders who need a trusted, high-capacity breaker that integrates smoothly with existing Eaton systems. Use cases include protecting feeder circuits in commercial panelboards, safeguarding three-phase machinery in light industrial setups, and serving as a reliable upgrade or replacement for aging or undersized MCCBs in compatible Eaton load centers.
