Key Features

• 125 A rated current
• 2-pole thermal-magnetic protection for 120/240V circuits
• CH frame, plug-on mounting
• Manufacturer: Eaton (Cutler Hammer line)

What this breaker does

The CH2125 provides overcurrent protection using a thermal-magnetic trip mechanism. It is a two-pole breaker rated for 125 A on 120/240V circuits, combining thermal (overload) and magnetic (short-circuit) trip elements.

• Protects two poles simultaneously for multi-wire branch circuits
• Thermal-magnetic trip provides overload and short-circuit response

Typical applications

The CH2125 is commonly used where 125 A two-pole protection is required on 120/240V circuits. Confirm load requirements and local code when selecting a breaker for a specific application.

• Feeder protection to subpanels where a 125 A breaker is appropriate
• Larger branch circuits sized for a 125 A breaker
• General branch-circuit protection when matched to load and code

Panel compatibility and mounting

This is a CH-frame, plug-on type breaker intended for panels and load centers designed to accept CH-frame plug-on breakers. Verify that your panelboard model accepts CH-frame breakers before ordering.

• Plug-on mounting for compatible Eaton/Cutler Hammer bus assemblies
• Confirm panel model and bus type for compatibility
