It's rated 400 A, 3-pole, with fixed settings — not adjustable in the field. This is a switch-disconnector for motor protection in IEC distribution, meaning it sits upstream of a contactor and handles the short-circuit and overload protection for a motor branch circuit. The PR222MP trip unit gives you thermal-magnetic curves (L and I protections) with a fixed I²t characteristic, so selectivity studies stay predictable.
Where it goes in a panel
This is a 3-pole unit that bolts into a panel — no DIN-rail clip. The T5L family uses a fixed front-panel mounting plate, so you'll need to account for the cut-out and busbar connections. It's sized for 400 A motor circuits, typically feeding a contactor downstream. The PR222MP trip unit is self-powered from the line side, so no auxiliary supply needed for the protection electronics.
