The MGP36350 is a Schneider Electric PowerPacT M series circuit breaker with an electronic trip unit, rated 350 A, 3-pole, 18 kA interrupting capacity at 600 VAC. It comes in a unit-mount form factor with lugs off the end for line and load connections. This is the part you spec into a 350 A feeder or large motor branch circuit where you need adjustable electronic trip curves rather than fixed thermal-magnetic protection.
Unit-mount design bolts directly into a panel or enclosure backpan. The lugs-off-end termination keeps cable entry clean for vertical bus or switchboard layouts.
Category code US10DE201205 classifies this under low-voltage power circuit breakers. Single-unit packaging — order one piece per line item.
