It also carries a 60 V DC rating, making it suitable for mixed AC/DC control circuits in industrial panels. That dual rating means one part number covers both installation types without oversizing the panel. The 400 V AC rated voltage matches standard three-phase line-to-line supplies; the 60 V DC rating covers control-voltage rails (48 V or 60 V nominal) common in relay and PLC cabinets. The 70 mm installation depth fits flush in shallow enclosures, and the IP20 body (IP40 at the handle area) protects against finger contact while allowing the toggle to protrude through a panel cutout.","metaTitle":"Siemens SENTRON 5SJ4118-7HG40 Miniature Circuit Breaker, C-C","metaDescription":"Siemens SENTRON 5SJ4118-7HG40 1-pole MCB, C-curve, 10 kA per EN 60898, 15 kA per IEC 60947-2, 400 V AC / 60 V DC, 18 mm wide, active production.
