It protects branch circuits against overload and short-circuit in residential and infrastructure panels, with a 10 kA breaking capacity at 400 V AC per both EN 60898 and IEC 60947-2. The B-curve means it trips between 3 and 5 times rated current — suited for resistive or general-purpose loads where inrush is low, like lighting or heater circuits. ## Panel fit and mounting Occupies 3 modular width units (54 mm) on a DIN rail, with a 76 mm depth and 70 mm installation depth. Mounts in any position. The IP20 rating applies only with connected conductors — standard for enclosed distribution boards. Sealable cover option is built in, and the housing is halogen-free and silicon-free, which matters if the panel is in a clean environment or near sensitive equipment.","metaTitle":"Siemens 5SL4302-6 SENTRON MCB, 3-pole B-curve 2A 400V 10kA","metaDescription":"Siemens 5SL4302-6 SENTRON miniature circuit breaker, 3-pole, B-curve, 2A, 400V AC, 10kA breaking capacity per EN 60898 & IEC 60947-2.
