LC3400F - 400Amp Max. *Frame Only*

LC3400F - 400Amp Max. *Frame Only*

The LC3400F is a 400-amp, 3-pole Type LC thermal-magnetic circuit breaker frame rated at 40°C. Because this unit is supplied as FRAME ONLY, it's intended for applications where the frame meets your existing equipment requirements and compatible components are handled separately. The Type LC configuration, three-pole arrangement, interrupting rating, temperature rating, dimensions, and frame-only configuration should all agree with the application. Properly selected, completed with compatible components, installed, and used within its specified ratings, the LC3400F 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 information was provided for the LC3400F. Do not assume those certifications.

Where It Works Best

The LC3400F is best considered for compatible existing or legacy electrical equipment requiring a 400A, 3-pole Type LC frame. Since this is a frame-only product, confirming exactly what the equipment requires is especially important.

On the electrical side, confirm the application matches the stated interrupting rating: 25kA at 600VAC, 35kA at 480VAC, or 50kA at 240VAC, as applicable. Also check the 40°C rating against the installation requirements.
