LMD63B700L - 700Amp Circuit Breaker

LMD63B700L - 700Amp Circuit Breaker

When the catalog number is LMD63B700L, don't let the 700A rating do all the talking. There's quite a bit more to match. This is a 3-pole, 600VAC molded case circuit breaker in the LMD6 family, built on an LMD frame with a thermal-magnetic trip unit. It's specified as a standard 40°C breaker, with an interrupting rating of 25 kAIC at 600V and 50 kAIC at 480V. Those are the electrical basics. The connection arrangement also helps with identification: TA3K500 lugs are fitted on both the line and load sides, and they're rated for 1/0 AWG through 500 kcmil copper or aluminum conductors.
