• Thermal-magnetic trip unit: Combines thermal (overload) and magnetic (short-circuit) sensing to provide stable, predictable protection performance with quick, consistent trips.
• OEM-matched compatibility: Works with matching Eaton OEM load centers and panelboards for straightforward installation and integrated protection across your electrical system.
• Versatile for multiple sectors: Suitable for residential, commercial, and light industrial applications where reliable branch-circuit protection is essential.

Technical snapshot

• Manufacturer: Eaton
• Part Number: CC3125
• Type: Thermal-magnetic molded case circuit breaker
• Amperage Rating: 125 A
• Voltage Rating: 240 V
• Number of Poles: 3
• Application: Branch circuit overcurrent and short-circuit protection

The 3-pole design ensures simultaneous interruption of all three conductors, an important safety feature in 3-phase or multi-wire configurations. The 125 A rating positions this breaker for sizable branch circuits, while the 240 V rating covers standard 240 V loads common in many residential and commercial panels. The compact form-factor helps you maximize panel capacity without compromising protection.

Practical use cases

• Upgrading or replacing an existing 125 A circuit breaker in a panelboard or loadcenter where space is at a premium.
• Providing reliable protection for 240 V circuits in small-to-medium commercial spaces, workshops, or light industrial setups.
• Integrating with Eaton-branded load centers for a cohesive protection strategy across the electrical distribution system.

What to expect in installation and maintenance

• Designed for straightforward installation with compatible Eaton panelboards and loadcenters.
• Thermal-magnetic protection reduces nuisance trips and improves reliability over time.
• Routine inspection should verify the breaker remains firmly seated in the bus and that the load does not routinely approach the 125 A rating.
