125 Amp 2 Pole Standard CH Circuit Breaker · Eaton CH2125
What this product is for
The Eaton CH2125 is a 2-pole 125A plug-in circuit breaker used in Type CH loadcentres for branch circuit protection on 120/240V systems. It is intended to protect conductors and connected equipment from overloads and short circuits where a common-trip 2-pole breaker is required.
Use for
- Type CH residential and light commercial loadcentres
- 120/240V branch circuits requiring a 2-pole 125A breaker
- Applications needing common trip across both poles
- New installations, service upgrades, and breaker replacement where CH series compatibility is required
Avoid for
- Panels that do not accept Eaton Type CH breakers
- Bolt-on breaker applications
- Applications requiring a higher interrupting rating than 10 kAIC
- Installations where local code or equipment labelling calls for a different breaker series
Best for
Electricians and contractors replacing or specifying a high-amperage 2-pole breaker in an Eaton Type CH panelboard or loadcentre. This is a fit-driven product, so panel compatibility and required ampacity matter more than general breaker appearance.
Installed in
Typically installed in Eaton Type CH loadcentres using two 3/4 in spaces. Product dimensions are approximately 3.75 in D x 2.5 in W x 2.75 in H (95 mm x 64 mm x 70 mm).
Why this product exists
This breaker provides overcurrent protection for larger 120/240V branch circuits in CH-format panels while keeping the installation in the correct listed breaker family. Using the specified breaker type helps maintain panel compatibility and inspection acceptance.
Compared with similar products
Compared with lower-amperage CH breakers, the CH2125 is used for heavier branch circuit loads. Compared with bolt-on or other breaker families such as BR, this model is a plug-in Type CH breaker and should only be used where the panel label permits it. As a typical trade rule, continuous loads are commonly sized to 80 percent of breaker rating, so a 125A breaker is typically applied to loads up to about 100A continuous. Actual loading depends on equipment rating, conductor sizing, installation conditions, and local electrical code.
