This is the variant you spec into a panel where you need all-pole disconnection and protection against sinusoidal AC, pulsating DC, and smooth DC fault currents — Type B covers the full range, including variable-speed drive and UPS leakage. The 30 mA sensitivity provides personal protection against direct contact. The short-time delayed characteristic (SIGRES function) withstands brief inrush without nuisance tripping. Supply voltage range is 70 V to 440 V AC. The 70 mm installation depth matches standard distribution board cutouts. The silicon-free construction is relevant for automotive or aerospace panel environments where silicone outgassing can contaminate contacts or optics. Rated short-circuit current (IEC 61008-1) is 0.8 kA, with a maximum permissible series fuse short-circuit current of 100 A. The conditional short-circuit rating of 10 kA applies when backed by an upstream protective device — typical for a sub-distribution board fed from a main breaker. Overvoltage category III suits fixed installation downstream of the utility meter. This covers most indoor industrial and commercial environments; if the panel sits in an unconditioned space that sees below -25 °C, the storage minimum is fine but operation requires the warmer range.","metaTitle":"Siemens 5SV3346-4 SENTRON RCCB, 4P, Type B, 63 A, 30 mA, 400","metaDescription":"Siemens 5SV3346-4 SENTRON RCCB, 4-pole, Type B, short-time delayed, 63 A, 30 mA, 400 V AC.
