LC3300F - 300Amp Max. *Frame Only*

LC3300F - 300Amp Max. *Frame Only*

The LC3300F is a 300-amp, 3-pole Type LC thermal-magnetic circuit breaker frame rated at 40°C. It is supplied as FRAME ONLY, an important distinction when you're matching parts for equipment already in service. When properly selected, assembled with compatible components, installed, and operated within its specified ratings, the LC3300F is built to last in its intended application.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance details were provided for the LC3300F, so do not assume any.

Where It Works Best

The LC3300F makes the most sense in compatible existing or legacy equipment that calls for a 300A, 3-pole Type LC frame. This is replacement-focused equipment, so matching the details matters.

Check the required system voltage and available fault-current requirements against the frame's stated AIC ratings of 25kA at 600VAC, 35kA at 480VAC, and 50kA at 240VAC. The 40°C rating should also agree with the application requirements.
