The Siemens 5SL4632-8 is a SENTRON miniature circuit breaker with four poles configured as 3P+N, a D tripping characteristic, and a 32 A rated current at 30 °C. It switches the neutral conductor and carries a 10 kA breaking capacity per both EN 60898 and IEC 60947-2, so it coordinates with standard residential and light commercial distribution boards without upstream fuse derating. Rated 400 V AC for multi-phase operation, with a maximum of 440 V AC.
Occupies 4 modular width units (72 mm wide) on a DIN rail, with an installation depth of 70 mm and a total depth of 76 mm. Mounting position is unrestricted, and the enclosure carries IP20 protection with connected conductors. The sealable design and touch-protection feature meet the requirements of overvoltage category III, pollution degree 2 environments typical of final distribution circuits.
