The Schneider Electric MGP0252L2N is a PowerPacT 4 molded case circuit breaker (MCCB) rated 25 A at 40 °C, 1P+N (L2-N), 230 V AC 50/60 Hz, with a TM-D thermal-magnetic trip unit providing LI protection (overload and short-circuit). It carries a 25 kA Icu and Ics at 415 V AC, Category A utilization, and is suitable for isolation per BS EN 60947-2. The unit is panel-mounted, fits a 2-module (35 mm) footprint, and can be mounted horizontally or vertically.
The 8 kV impulse withstand voltage (Uimp) means it handles transient surges common in industrial panels without flashover. The 750 V rated insulation voltage (Ui) gives headroom for the internal isolation path. The 20000-cycle mechanical durability and 20000-cycle electrical durability at rated current give a sense of the service life under normal switching — though in distribution duty, it's mostly sitting closed.
This is a distribution-circuit breaker — it protects branch circuits in panelboards, subpanels, or directly on a backplate in a control cabinet. The 1P+N configuration (switching the line, monitoring neutral) is typical for single-phase loads in commercial or light industrial distribution. The panel-mount form factor and 2-module width (35 mm) mean it fits standard DIN-rail or backplate layouts, though it's not a snap-on DIN rail breaker — it's bolted to the backplate.
