Eaton CHH3125 - 125 A, 3-Pole Circuit Breaker | AmpState

Meet the Eaton CHH3125 — a 125 A, 3-pole molded case circuit breaker designed to deliver precise, reliable protection for your electrical panels. Built for dependable branch circuit overcurrent and short-circuit protection, this unit is an essential component in panelboards and load centers across residential, commercial, and light industrial settings. From AmpState, this breaker combines space-efficient design with Eaton’s trusted trip technology to keep circuits safe and downtime to a minimum.

Key Features that Matter

• Compact molded-case design maximizes panel space, letting you fit more protected circuits without crowding wiring or bus bars.
• Thermal-magnetic trip unit provides stable, repeatable protection, delivering fast responses to short circuits while minimizing nuisance trips from normal inrush currents.
• Seamless compatibility is engineered to work with matching OEM load centers and panelboards, ensuring a cohesive protection system with manufacturer-aligned performance.
• Versatile for multiple environments suited for residential, commercial, and light industrial applications where dependable protection is essential.

Why This Breaker Stands Out

The CHH3125 is more than a block of circuitry — it’s a thoughtfully engineered protection device designed to integrate smoothly into Eaton-based panel architectures. Its 3-pole configuration is ideal for 3-phase feeders, enabling balanced protection across phases while maintaining a compact footprint. With a 125 A rating, it’s well-suited to protect feeders and downstream loads in service panels, commercial equipment racks, and light industrial panels where both space and reliability matter. By choosing an Eaton molded-case breaker, you’re opting for a proven trip characteristic and predictable performance that installers and facility managers can trust over years of operation.
