The MGN60641 is a C60H miniature circuit breaker from the Multi9 range, rated 20 A at 50 °C with a C-curve trip characteristic (magnetic trip at 8.5 x In ±20 %). The 30 kA Icu at 240 V AC phase-to-phase (EN/IEC 60947-2) tells you it can safely interrupt a fault up to that level without welding its contacts or cascading upstream; the 25 kA Icu at 125 V DC means it also handles DC distribution panels, common in battery-backed control circuits or solar combiner boxes. For a panel OEM wiring a 20 A lighting or small-power subfeed, this breaker meets it where it is: 3-pole, 35 mm DIN rail mount, tunnel terminals accepting 1–25 mm².
The 54 mm width (6 x 9 mm pitches) occupies three standard module spaces in the enclosure. IP20 rated, so it lives inside a closed panel — no washdown exposure. The toggle gives local ON/OFF indication and a contact position indicator confirms isolation status (suitability for isolation is certified per EN/IEC 60947-2). Earth-leakage protection requires a separate block, not integrated.
