Accepts solid or stranded conductors from 0.75 to 25 mm²; screw terminals torqued to 2.5–3 N·m. Mounting position is unrestricted, and the housing carries touch protection (IP20 with conductors connected). Halogen-free and silicon-free construction suits environments sensitive to outgassing — clean rooms, food processing, medical. Rated for ambient temperatures from -25 to +45 °C operating, with storage range -40 to +75 °C. Withstands periodic 55 °C at 95% humidity. Overvoltage category III, energy limiting class 3. Sealable for tamper evidence. No neutral conductor switching.","metaTitle":"Siemens 5SN6306-6CN SENTRON MCB, 3P B 6A, 6kA, 400V","metaDescription":"Siemens SENTRON 5SN6306-6CN miniature circuit breaker, 3-pole, B-curve, 6 A, 6 kA per EN 60898, 400 V AC.
