Eaton HMCPS050K2W - 50 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet Eaton HMCPS050K2W — a 50A, 600V, 3-pole molded case circuit breaker engineered to protect your panelboards and loadcenters with precise, dependable performance. This compact device is built to fit snugly where panel space is at a premium, while delivering robust protection for critical circuits.

Why this breaker stands out

• Compact molded case design saves valuable real estate inside panelboards and loadcenters, making it easier to organize feeders and branch circuits without sacrificing protection.
• Thermal-magnetic trip unit delivers stable, repeatable protection across a range of temperatures and fault conditions, helping prevent nuisance trips and ensuring fast disconnection when needed.
• OEM-compatible integration is designed to pair with matching Eaton panelboards and loadcenters, enabling a smooth replacement or upgrade without adapters or custom work.
• Versatile for multiple environments ideal for residential, commercial, and light industrial applications where reliable 3-phase protection matters.

Ideal use cases

• Upgrading or expanding 3-phase feeders in commercial panels, retail storefronts, or small office spaces.
• Protecting HVAC, lighting, or motor circuits in light industrial settings where consistent trip behavior is critical.
• Retrofits in existing Eaton OEM panelboards and loadcenters to maintain system protection while simplifying maintenance.

How it protects your system

The HMCPS050K2W uses a thermal-magnetic trip mechanism to respond to overloads and short circuits. The thermal element handles sustained overloads, while the magnetic element provides instantaneous disconnection on high fault currents. This combination minimizes equipment damage, reduces fire risk, and helps your electrical system reset quickly after a fault.
