Siemens SENTRON 5SY7315-7CC — 1.6 A C-Curve MCB for Industrial Panels
It switches 400 V AC circuits and is rated for a 50 kA breaking capacity under IEC 60947-2 — that's the fault-clearing capability for industrial panel feeders where high prospective short-circuit currents are expected. For UL 1077 and CSA C22.2 No. 235 installations, the interrupting rating is 5 kA. The 54 mm width (3 width units) fits standard enclosure cutouts. Terminal capacity accepts 0.75 to 35 mm² solid or stranded copper, with a screw-terminal torque range of 2.5 to 3.5 N·m. IP20 protection with conductors connected — suitable for enclosed panel mounting.
Panel Integration & Compliance
The breaker is sealable, halogen-free, and silicon-free — relevant for food-grade or clean-room panels where outgassing must be controlled. Overvoltage category III suits fixed-installation distribution boards. The neutral conductor is not switched (3-pole only, no switched neutral). Touch protection is included on the terminals.
