The Siemens 5SJ4110-8HG41 is a 1-pole miniature circuit breaker from the SENTRON 5SJ4 series, carrying a D tripping characteristic. Breaking capacity is rated 10 kA per EN 60898 and 15 kA per IEC 60947-2, so it clears faults up to those levels without cascading upstream. The 18 mm width (1 modular unit) snaps onto standard DIN rail, and the IP20/IP40 enclosure suits panel installation with connected conductors.
Ratings and environment
Rated for AC 400 V and DC 60 V maximum. The insulation voltage (Ui) is 440 V AC. Vibration resistance is specified at 50 m/s² over 25–150 Hz and 60 m/s² at 35 Hz (4 s), so it holds up on machinery with moderate vibration.
