Eaton HMCP030H1C - 30 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton HMCP030H1C—a reliable 30A, 600V, 3-pole molded case circuit breaker built to safeguard branch circuits in panelboards and load centers. Designed for lasting performance, it combines compact size with robust protection that technicians can trust in everyday electrical installations.

Why this breaker stands out:

• Compact molded-case design makes efficient use of panel space, streamlining layouts in tighter enclosures and simplifying retrofits in existing panels.
• Thermal-magnetic trip unit delivers stable, repeatable protection by accurately sensing both overloads and short circuits, reducing nuisance trips while safeguarding equipment.
• Three-pole configuration provides comprehensive three-phase protection, ideal for commercial and light industrial applications where balanced, reliable circuit interruption is essential.
• 600V rating expands compatibility with higher-voltage circuits common in non-residential settings, offering flexibility for a range of panelboard deployments.
• OEM-compatible design is engineered to pair with matching Eaton OEM load centers and panelboards, ensuring plug‑and‑play installation and consistent performance across the system.
• Versatile application suited for residential, commercial, and light industrial environments that require dependable branch-circuit protection and quick fault isolation.

How it protects your system matters. The dual-action trip—thermal for gradual overloads and magnetic for sudden short circuits—means circuits trip promptly when faults occur, while normal operation stays uninterrupted during everyday load fluctuations. This translates to reduced downtime, safer motor and line protection, and simpler maintenance in busy electrical rooms.

Practical uses and scenarios:

• Install in commercial distribution panels to protect critical motor loads up to 30A in three-phase circuits.
  Example: small HVAC or processing equipment that runs on 3-phase power.
• Upgrade or replace aging breakers in OEM load centers to maintain coordinated protection and panel compatibility.
  Example: modernization of a retail storefront electrical system.
• Use in light industrial starter panels where compact form factor and reliable protection are priorities for space-constrained installations.
