MGP36600SA — PowerPact M Unit Mount Breaker, 600A
The MGP36600SA is a Schneider Electric PowerPact M unit mount breaker rated 600A continuous, 3-pole, with an interrupting capacity of 18 kA at 600 VAC. It comes with an electronic trip unit, a 120V shunt trip for remote opening, and lugs off the end for line/load connections. This is a full-frame, high-current breaker sized for main or large feeder protection in switchboards, panelboards, or standalone enclosures.
600A continuous rating means this breaker carries a full 600A load without tripping under normal conditions — sized for a main disconnect or a large feeder feeding a downstream subpanel or heavy motor load center. The electronic trip unit offers adjustable long-time, short-time, and instantaneous pickup — field-configurable for coordination with downstream breakers, unlike a fixed thermal-magnetic trip.
Deployment Context
This is a unit mount breaker — it bolts into a switchboard or panelboard mounting pan, not a DIN rail. The lugs off the end accept cable or bus connections from the line side (top) and load side (bottom). The 120V shunt trip allows remote tripping from a fire alarm system, emergency stop circuit, or PLC output. Panel builders should verify lug wire range and torque specs from the PowerPact M installation guide before terminating.
