Siemens 5SP9232-7KC47 — SENTRON 2-pole MCB, C-curve, 32 A, 50 kA
The Siemens SENTRON 5SP9232-7KC47 is a 2-pole miniature circuit breaker rated 32 A with a C-curve tripping characteristic, designed for 400 V AC systems and certified to IEC 60947-2 with a 50 kA breaking capacity. It occupies 3 width units (54 mm) on standard DIN rail and accepts solid or stranded conductors from 0.75 mm² up to 50 mm² at the tunnel terminals, top and bottom.
The 2-pole configuration (2P) switches both phase conductors simultaneously, making it suitable for single-phase or split-phase branch circuits where full disconnection is required.
Mounts on standard DIN rail with screw fixing; installation depth is 92 mm. The IP20 rating applies with conductors connected — the front face is touch-protected per the product feature. Tunnel terminals accept solid or stranded copper from 0.75 mm² to 50 mm² (AWG 14 to 2). Tightening torque is 2.5 to 3.5 N·m (22 to 31 lbf·in). The terminals are sealable — a feature for installations requiring tamper-evident covers after commissioning.
