The MGP0201L2 is a Schneider Electric PowerPacT 4 molded case circuit breaker (MCCB), 1-pole, rated 20 A at 40 °C on a 230 V AC 50/60 Hz system. The toggle control and backplate mounting suit panel-board or enclosure integration, and it's rated for isolation per BS EN 60947-2.
This part is marked obsolete by the manufacturer. No official successor order code is listed in the lifecycle record. Don't assume a drop-in replacement from the same family; the PowerPacT 4 series has been superseded, and a parametric cross-check (poles, current, breaking capacity, voltage, trip curve) is needed before substituting.
Ics equals Icu here, so it can re-close after a fault at full rating. The 750 V rated insulation voltage (Ui) and 8 kV impulse withstand (Uimp) confirm it's built for distribution panels, not just branch circuits. The 1-pole, L2 phase connection means it's a single-pole breaker for a 230 V line-to-neutral or line-to-line circuit — not for a 3-phase main.
