Eaton HMCPS100R3C - 100 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Eaton HMCPS100R3C is a 100A, 600V, 3-pole molded case circuit breaker purpose-built to protect your panelboards and load centers from overloads and short circuits. Designed for dependable branch circuit protection, this device combines compact footprint with powerful performance, helping you maximize panel space without compromising safety.

• Compact molded-case design optimizes panel layout and frees space for additional circuits, making it ideal for tight electrical rooms and crowded panels.
• Thermal-magnetic trip unit delivers stable, repeatable protection by coordinating overcurrent and instantaneous fault response. The thermal element handles sustained overloads, while the magnetic element reacts quickly to short circuits to reduce damage and downtime.
• OEM panelboard compatibility engineered to mate with matching Eaton load centers and panelboards, ensuring proper fit, consistent trip characteristics, and straightforward substitution during upgrades or service revisions.
• Three-pole configuration for 3-phase systems supports commercial and light industrial applications where three-phase feeders are common, while still suitable for select residential or mixed-use panel layouts that require a 3-pole solution.
• Rugged, reliable protection for a range of environments from small commercial spaces to light industrial applications, where dependable protection and space efficiency are priorities.

How this model solves real-world problems

• When upgrading an aging panel or implementing a new three-phase feeder, the HMCPS100R3C provides a precise 100A protection point with a clear, predictable trip profile—minimizing nuisance trips and keeping critical loads safe.
• In space-constrained installations, the compact molded-case design lets you fit more circuits in the same footprint, simplifying panel design and wiring layouts.
• For facilities with Eaton OEM panels, this breaker ensures electrical coordination and compatibility, reducing installation time and potential compatibility issues during maintenance or replacement.

Ideal for: electrical contractors, facilities managers, and maintenance teams working in residential, commercial, and light industrial settings who need a reliable, space-efficient 3-pole breaker for 3-phase service or main/branch circuit protection.
