The MGP0162L12 is a Schneider Electric PowerPacT 4 molded case circuit breaker — 2-pole, 16 A rated current at 40 °C, with a TM-D thermal-magnetic trip unit providing LI protection (overload and short-circuit).
The 25 kA Icu/Ics at 415 V AC indicates the breaker can handle high fault currents typical of a main or submain distribution panel.
Mounts to a backplate (panel-mounted), not a DIN rail. It occupies a 2-module width at 35 mm per module. The mounting position is flexible — horizontal or vertical — which helps in tight enclosures. The toggle control is manual; no motor operator or shunt trip is built in. Rated insulation voltage is 750 V, impulse withstand 8 kV, so it has decent clearance for 415 V systems. Mechanical durability is 20,000 cycles, electrical durability 20,000 cycles at rated load (10,000 at 2x In).
