It's rated for 400 V AC at 50 Hz and up to 72 V DC, so it handles standard single-phase lighting and control circuits as well as DC auxiliary supplies in the same 18 mm-wide DIN-rail slot. The 6 kA breaking capacity per EN 60898 covers most residential and light commercial panel fault levels; the 15 kA rating per IEC 60947-2 gives you headroom for industrial distribution boards where the prospective short-circuit current is higher. That dual rating means you can spec it into a panel that needs to meet either standard without swapping parts. At 18 mm wide (one modular unit), it fits a dense panel layout. Accepts solid conductors up to 35 mm² — enough for the feed-through on a sub-distribution board. ## Environmental range Rated for -40 °C to 75 °C ambient, so it's usable in unheated enclosures, cold storage areas, or outdoor cabinets without derating for low temperature. The 10 000 mechanical operating cycles cover frequent switching in machine control panels.","metaTitle":"Siemens 5SN6110-8CP MCB, 1-Pole C-Curve, 6 kA EN 60898","metaDescription":"Siemens 5SN6110-8CP 1-pole MCB, C-curve, rated 400 V AC / 72 V DC.
