LCP36400MT - 400 Amp Circuit Breaker

LCP36400MT - 400 Amp Circuit Breaker

The LCP36400MT is a 400-amp, 3-pole Type LCP molded case circuit breaker with a thermal-magnetic trip. It's rated for 60Hz and 40°C, with interrupting ratings of 25kA at 600VAC, 35kA at 480VAC, and 50kA at 240VAC. Those numbers are especially useful when you're trying to match a breaker already installed in existing equipment.

Where It Works Best

The LCP36400MT makes the most sense in compatible existing or legacy equipment that specifically requires a 400A, 3-pole Type LCP thermal-magnetic breaker.

When checking a potential replacement, pay close attention to the system voltage and available fault current. Depending on the operating voltage, the breaker is rated 25 kA at 600 VAC, 35 kA at 480 VAC, and 50 kA at 240 VAC.
