LMD63B700 - 700Amp Circuit Breaker

LMD63B700 - 700Amp Circuit Breaker

A 700A breaker isn't enough of a description when you're trying to match what's already installed. With the LMD63B700, you've got a much better set of details to work from. It's a 3-pole LMD-frame molded case circuit breaker rated for 600VAC, fitted with a thermal-magnetic trip unit, and specified as a standard 40°C breaker. Interrupting capacity is 25 kAIC at 600V and 50 kAIC at 480V. Those numbers help establish the electrical side of the match. Then you can move on to the physical details.
