LMD63B600L - 600Amp Circuit Breaker

LMD63B600L - 600Amp Circuit Breaker

With an LMD63B600L, I'd pay attention to more than the 600A stamped on the breaker. This is a 3-pole, 600VAC molded case circuit breaker in the LMD6 family, using an LMD frame and a thermal-magnetic trip unit. It's specified as a standard 40°C breaker. The interrupting ratings give you two more useful checkpoints: 25 kAIC at 600V and 50 kAIC at 480V.

Where It Works Best

The LMD63B600L comes into focus when you're maintaining existing or legacy electrical equipment and need to match this particular LMD breaker configuration.

Start with 600A and three poles. Then confirm the 600VAC rating and thermal-magnetic trip. At 600V, the breaker is rated 25 kAIC. At 480V, it's 50 kAIC.
