Eaton HMCP100R3C - 100 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton HMCP100R3C — a robust 100 A, 600 V, 3-pole molded case circuit breaker designed to deliver dependable branch circuit protection for panelboards and loadcenters. Available through AmpState, it combines compact sizing with precise, predictable performance, making it a smart choice for modern electrical distributions.

Why this breaker stands out

• Space-efficient molded case design frees up panel real estate, letting you optimize circuit density without sacrificing protection.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining thermal overlap protection with magnetic short-circuit sensing for fast, reliable response when faults occur.
• OEM-ready compatibility engineered to integrate smoothly with matching Eaton OEM loadcenters and panelboards, simplifying replacements and upgrades.
• Versatile for multiple sectors ideal for residential, commercial, and light industrial applications where durable, predictable protection matters.

Technical snapshot

• Amperage rating: 100 A
• Voltage rating: 600 V
• Number of poles: 3
• Type: Thermal-magnetic molded case circuit breaker

Ideal use cases and practical applications

• Panelboard upgrades: replace aging breakers in existing installations to regain reliable protection while preserving panel layout.
• New construction and renovations: a compact, easy-to-install solution that fits tight electrical spaces without compromising safety.
• Commercial lighting and small business electrical rooms: robust protection for multi-wire branch circuits with clear, predictable trip characteristics.
• Residential service panels requiring dependable 3-pole protection for multi-phase circuits or equipment clusters.

What makes it a smarter choice

Compared with breakers that rely solely on thermal trip mechanisms, the HMCP100R3C’s thermal-magnetic system delivers rapid magnetic protection for high-energy short-circuit events, reducing fault damage and downtime. Its compact footprint and OEM-friendly design minimize retrofit headaches, while the 3-pole configuration provides balanced protection across three-phase or multi-wire circuits typical in modern installations.

Tips for installation and longevity

• Verify panel compatibility with HMCP series breakers and follow the panelboard manufacturer’s torque specs for terminal connections to ensure secure, reliable fastening.
• Coordinate protection with/around downstream devices to maintain proper selectivity and avoid nuisance trips during startup surges.
• Label circuits clearly after installation to support quick fault isolation and routine maintenance checks.

With the Eaton HMCP100R3C, you gain a compact, dependable, and compatible solution that protects people and property while helping you maximize panel space and uptime. Tap into trusted Eaton engineering and the availability and support you expect from AmpState.
