The MGP36600LC is a 600 A, 3-pole PowerPacT M unit mount breaker with an electronic trip unit, rated 18 kA at 600 VAC. That matters when you need selectivity downstream or want to dial in the trip for a specific load like a large motor or a transformer primary.
Termination and panel fit
Copper lug terminations, lugs off end — that means the line and load conductors land on the end of the breaker, not the side. In a switchboard or unit-mount enclosure, that orientation keeps the cable bending radius clear of adjacent poles and bus bars. The 600 A frame is a substantial piece of gear; plan for the physical space and the lug torque values in the installation manual.
