1-pole C-curve MCB for 400 V AC panels
The Siemens 5SN6102-8CP is a 1-pole miniature circuit breaker from the SENTRON 5SN series, rated 400 V AC with a C-curve tripping characteristic. It carries a 6 kA breaking capacity per EN 60898 and a 30 kA rating per IEC 60947-2 — the higher IEC figure matters when the breaker sits in an industrial panel where fault current can exceed the residential standard. The 72 V DC maximum rating means it also handles DC control circuits, though the DC breaking capacity is not separately stated. It occupies a single 18 mm modular width on DIN rail, with a 76 mm depth and 70 mm installation depth, so it fits standard distribution boards without extra space.
DIN-rail integration and environment
Snap-on DIN-rail mounting, 18 mm width, 76 mm depth. Accepts solid conductors up to 35 mm² — enough for the incoming feed on most sub-distribution boards.
