The Siemens SENTRON 5SL4532-8 is a 1P+N miniature circuit breaker rated 32 A at 230 V AC, with a D tripping characteristic and a 10 kA breaking capacity per EN 60898 and IEC 60947-2. The D-curve (10–20× In) is sized for loads with high inrush currents — motor starters, small transformers, or lighting ballasts — where a B or C curve would nuisance-trip on startup. The 10 kA SCCR at 230 V means it safely interrupts a bolted fault up to that level without cascading to an upstream device, per the standard's certification.
Dimensions and panel fit
The 5SL4532-8 occupies 2 width units (36 mm) on a DIN rail, with a depth of 76 mm and a height of 90 mm. The 70 mm installation depth leaves clearance behind the rail for wiring. IP20 with connected conductors — suitable for enclosed distribution boards, not for wet or dusty environments. Mounting position is any, so it fits vertical or horizontal busbars without derating.
