The Siemens SENTRON 5SY5132-7KK11 is a 1-pole miniature circuit breaker rated 32 A with a C tripping characteristic. It breaks 10 kA at 400 V AC (EN 60898) and 10 kA at 220 V DC (EN 60898-2). The C-curve means it trips between 5 and 10 times rated current — standard for mixed resistive and moderate inductive loads like control transformers, contactor coils, and general panel circuits. The 10 kA SCCR at both AC and DC tells you it can interrupt faults up to that level without upstream backup in a properly coordinated panel.
Environmental and compliance notes
Halogen-free and silicon-free construction suits rail and industrial environments where outgassing or silicone contamination affects contacts or optics. Sealable for lockout/tagout compliance. Overvoltage category III means it's rated for fixed-installation distribution panels, not just downstream equipment. Protection class IP20 with connected conductors — expected for a DIN-rail MCB; no washdown rating.
