Eaton HMCP250A5 - 250 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton HMCP250A5 — a rugged 250 A, 600 V, 3-pole molded-case circuit breaker designed to protect your electrical distribution with precision. Built for dependable branch circuit overcurrent and short-circuit protection, it slots into panelboards and loadcenters with a compact footprint that helps maximize usable space without compromising safety.

The thermal-magnetic trip unit delivers stable, repeatable protection across a range of loads. The thermal element monitors sustained overcurrent to prevent nuisance trips during normal operation, while the magnetic element provides an instantaneous response to high fault currents, safeguarding wiring and connected equipment from severe damage.

Designed for seamless compatibility, the HMCP250A5 works with matching OEM loadcenters and panelboards, ensuring a cohesive, reliable protection scheme in your electrical distribution. Its molded-case construction combines durability with ease of maintenance, making it a practical choice for both new installs and panel retrofits.

Ideal for residential, commercial, and light industrial applications, this 3-pole breaker is suited for three-phase distribution or multi-wire branch circuits in modern panel assemblies. Use it where you need robust protection for main feeds, feeders, and branch circuits, while maintaining clear, organized panel layouts.
