Mounting position is unrestricted; ambient range is -25 to +45 °C, with periodic tolerance to +55 °C at up to 95% humidity. Rated 4.5 kA per both EN 60898 and IEC 60947-2 at 400 V AC, this 4-pole MCB with C-curve (2 A) clears faults up to that level without cascading upstream — sized for residential and light commercial sub-distribution. Energy limiting class 3 means it lets through less let-through energy on a fault, improving downstream device protection. Halogen-free and silicon-free construction, with IP20 touch protection (finger-safe when conductors are connected). Overvoltage category 3 per IEC 60664. Classification per DIN EN 61346-2 and DIN EN 81346-2 is F (protective device). Suitable for residential buildings and infrastructure.","metaTitle":"Siemens 5SL3402-7 SENTRON MCB, 4P C 2A, 4.5kA, 400V AC","metaDescription":"Siemens 5SL3402-7 SENTRON 4-pole MCB, C-curve, 2A rated, 4.5kA breaking capacity per EN 60898. 400V AC, 72mm wide.
