LA3125PR - 125Amp Circuit Breaker

LA3125PR - 125Amp Circuit Breaker

The LA3125PR is a 125-amp, 3-pole Type LA fusible circuit breaker for your compatible electrical equipment using an LA3400PRF frame. Check the frame, pole count, voltage, interrupting rating, dimensions, and existing installation details. When those specifications line up, the LA3125PR is intended to provide the form, fit, and function needed for compatible existing and legacy equipment. Properly selected, installed, and kept within its specified ratings, it's built to last.

Key Features and Benefits

Material Compliance and Certifications

No specific material-compliance information or certifications were provided for the LA3125PR, so do not assume certifications such as UL or material standards such as RoHS and REACH.

Where It Works Best

The LA3125PR makes the most sense in existing and legacy electrical systems that call for its particular combination of 125 amps, three poles, Type LA construction, LA3400PRF frame, and TRI-PAC® DE-ION® fusible circuit breaker design.

For replacement work, start with the part number, then check the rest of the breaker. Make sure the 125A rating and three-pole configuration agree with the application. Next, confirm the system voltage and required interrupting capacity against the breaker ratings of 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC. Also check the 40°C rating and physical footprint.
