Siemens 5SP9350-7KC47 — 50 A, 50 kA SENTRON MCB for Industrial Feeder Protection
Installation and Panel Fit
Mounts on standard DIN rail or via screw fixing. Occupies 4.5 width units with an installation depth of 92 mm — verify this against your enclosure depth if replacing a shallower unit like the 5SP4380-7 (70 mm depth). Tunnel terminals top and bottom accept conductors without lugging. IP20 with connected conductors means the breaker is touch-safe once wired; the enclosure must provide additional ingress protection for washdown environments.
Shock resistance per IEC 60068-2-27: 150 m/s² at 11 ms half-sine. Vibration resistance per IEC 60068-2-6: 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz for 4 seconds. Mechanical endurance: 20 000 switching cycles typical.
