Meet the Eaton HMCP100L3C — a 100A, 600V, 3-pole molded case circuit breaker engineered for reliable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Whether you’re wiring a residential panel, a commercial distribution, or a light industrial setup, this breaker delivers steady performance when it matters most.
Ideal use cases include upgrading existing panels, adding circuits in new build-outs, or replacing aging protection in panelboards where space is limited. The HMCP100L3C helps you maintain electrical safety, reduce nuisance trips, and simplify maintenance with a single, dependable device built to perform across varied environments.
Why this matters When you choose a breaker with a compact form factor, precise trip characteristics, and official compatibility with Eaton panels, you minimize compatibility headaches and maximize protection consistency across your electrical system. This is protection that scales from a home service panel to light-industrial distribution without the need for awkward adapters or mismatched components.
