Its 6 kA breaking capacity per EN 60898 (also rated 6 kA per IEC 60947-2) covers most residential and light commercial distribution boards where the prospective short-circuit current stays under that threshold. At 72 mm wide (4 modular width units) and 76 mm deep, it snaps onto standard DIN rail and occupies four 18 mm slots in a distribution board. Mounting position is unrestricted, so it fits vertical or horizontal rail layouts. Rated 32 A at 30 °C ambient. At 40 °C the continuous current drops to 30.31 A; at 45 °C to 29.44 A; at 55 °C to 27.58 A. The breaker itself is rated for ambient from -40 °C to 75 °C, with periodic exposure to +55 °C and 95% humidity. The breaker carries IP20 protection with connected conductors (finger-safe terminals). It is halogen-free and silicon-free, suitable for clean-room or sensitive environments. Touch protection is built in. The product is sealable for anti-tamper applications. Compliance documentation (RoHS, REACH, manufacturer declarations) is available with the order.","metaTitle":"Siemens 5SL6432-7BB SENTRON MCB, 4P C-32A 6kA","metaDescription":"Siemens SENTRON 5SL6432-7BB miniature circuit breaker, 4-pole, C-curve, 32 A rated, 6 kA breaking capacity per EN 60898.
