LI36400 - 400 Amp Circuit Breaker

LI36400 - 400 Amp Circuit Breaker

Need to match an LI36400 with your I-Line panelboard? This 400A, 3-pole molded-case circuit breaker features a thermal-magnetic trip design for 60 Hz at 40°C. It has an interrupting capacity of 200 kA at both 240VAC and 480VAC, and 100 kA at 600VAC. Remember, the A.I.C. rating changes with system voltage, so that’s important to consider!

Material Compliance and Certifications

The available specifications for the LI36400 don't provide exact UL, CSA, IEC, RoHS, REACH, or other certification and material-compliance information. Rather than fill in those blanks using information from a similar breaker, we don't assume any certification status here.

Where It Works Best

The LI36400 400A circuit breaker makes the most sense in existing or legacy I-Line panelboard equipment that already calls for this electrical and physical configuration.
