Product details

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.

Frequently asked questions

What is the breaking capacity of 5SP9350-7KC47?

50 kA per IEC 60947-2 at 400 V AC. This is the industrial-grade rating for high-fault-current panels, not the 10 kA residential rating per EN 60898 that some SENTRON siblings carry.

Will 5SP9350-7KC47 drop into a panel specified around 5SP4380-7?

The DIN-rail footprint and pole count match, but the installation depth is 92 mm versus 70 mm for the 5SP4380-7. Verify enclosure depth clearance before substitution. The breaking capacity is also higher (50 kA vs 10 kA), which may affect coordination.

Where can I buy 5SP9350-7KC47?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
