The MGN25080 is a 1 A, 1-pole C60H miniature circuit breaker from the Multi9 range, curve D, rated at 240 V AC phase-to-neutral. The 1 A rating at 50 °C per EN/IEC 60947-2 sets the continuous current the breaker carries without derating — if your ambient runs hotter, you need to account for that. The Ics (service breaking capacity) is 7.5 kA at 240 V AC, 50% of Icu, meaning after one fault at that level the breaker is still usable but should be inspected.
Deployment context
Snaps onto a 35 mm symmetrical DIN rail (EN 60715) and occupies 2 x 9 mm pitches (18 mm wide). The tunnel terminals accept 1 to 25 mm² rigid or flexible wire; strip length is 14 mm and tighten to 2 N·m. The toggle provides local ON/OFF indication and a contact position indicator confirms isolation status.
