Lead — integrator note
The Siemens 5SY4332-7CC11 is a 3-pole SENTRON miniature circuit breaker rated 32 A with a C tripping characteristic, breaking 10 kA at 400 V AC per EN 60898. It occupies 3 width units (54 mm) on the DIN rail and accepts conductors from 0.75 to 35 mm² solid or stranded. The design is rated for railway applications and carries overvoltage category III, making it suitable for fixed-installation branch circuits in industrial panels, mechanical engineering, and infrastructure where coordination with upstream devices matters.
Integration — panel and wiring fit
The combined terminal design at top and bottom accepts solid or stranded copper up to 35 mm², with a tightening torque range of 2.5 to 3.5 N·m. The enclosure is IP20 with connected conductors, and the breaker is sealable for tamper-evident applications. Halogen-free and silicon-free construction supports use in clean environments or where outgassing constraints apply.
