The MGN25084 is a C60H miniature circuit-breaker from the Multi9 range — a 1-pole, D-curve unit rated 6 A at 50 °C per EN/IEC 60947-2. The D-curve magnetic trip triggers at 12 x In ±20 %, so it tolerates the inrush of motor loads, transformers, or welding equipment without nuisance tripping.
Snaps onto 35 mm symmetrical DIN rail — standard panel layout, 18 mm per pole width, 2 module pitches. The 73 mm depth fits shallow enclosures; leave clearance for the toggle handle and wiring. Rated for isolation (EN/IEC 60947-2) with a visible contact-position indicator, so you can lock it out as a disconnecting means. Pollution degree 3 means it handles conductive dust and condensation typical of industrial control rooms. Ambient operating range -30 to 70 °C covers most plant-floor conditions without derating.
