The Siemens Betagard 5SL7232-8RC is a 2-pole miniature circuit breaker with a D tripping characteristic, rated 32 A at 415 V AC and a breaking capacity of 15 kA per both EN 60898 and IEC 60947-2. The D-curve tolerates high inrush currents before tripping magnetically, suiting loads like small motors or transformers. Rated for 415 V AC phase-to-phase or phase-to-neutral, with a maximum operating voltage of 440 V AC in single- or multi-phase operation.
Breaking capacity of 15 kA at 415 V per IEC 60947-2 means this breaker can safely interrupt a fault current up to 15,000 A without welding contacts or cascading failure upstream — enough for most industrial sub-distribution boards fed by a transformer in the 630 kVA range. Temperature derating is published: at 40 °C ambient it carries 30.4 A, at 50 °C it's 28.8 A, at 60 °C it's 27.52 A.
Width is 18 mm (2 modular units), depth 76 mm, height 90 mm, installation depth 70 mm. Touch protection is integrated, meaning live busbar and terminals are shielded to IP2X even with the breaker snapped in place.
