The MGN60875 is a 2-pole C60N miniature circuit-breaker from Schneider Electric's Multi9 range, rated 1 A at 50 °C with a C trip curve. The C curve (magnetic trip at 8.5 x In ±20 %) means it handles moderate inrush — typical for small motor or lighting loads — without nuisance tripping on startup, while still clearing a hard fault fast. Rated operational voltage goes up to 440 V AC, but the breaking capacity derates: 10 kA at 415 V, 6 kA at 440 V. That derating curve is the spec to check when you're coordinating with an upstream breaker in a 400 V panel. It's a thermal-magnetic trip unit, Category A (no intentional short-time delay), so it's a standard distribution MCB — not a selective breaker. The 2-pole version protects both legs of a single-phase circuit or one leg of a DC circuit (the network type is listed as DC,).
Mounting and integration — DIN rail, tunnel terminals, IP20
Width is 36 mm (2 modules at 18 mm each), height 81 mm, depth 73 mm — that 73 mm depth is the dimension to watch when the enclosure door or gland plate is tight; it's the body depth, not including the toggle throw. Strip length is 14 mm.
