The Siemens SENTRON 5SL3632-6 is a 4-pole miniature circuit breaker (3P+N) with a B tripping characteristic, rated at 32 A and 400 V AC. It breaks fault currents up to 4.5 kA under both EN 60898 and IEC 60947-2 — the dual rating means it qualifies for residential/infrastructure panels (EN 60898) and industrial control circuits (IEC 60947-2) without a separate coordination study.
In a 3P+N configuration the neutral pole switches with the phases, so it suits single-phase loads distributed across the three phases in a 400 V panel. Terminals accept solid or stranded conductors from 0.75 to 25 mm²; tighten to 2.5–3 N·m. Rated for ambient temperatures from -25 to +45 °C (operating) and -40 to +75 °C (storage). IP20 with connected conductors — panel-mount only, not for wet or outdoor locations without an enclosure.
