Type B means it catches smooth DC fault currents that a standard AC/Type A device would miss, so it's the right choice for modern power-electronics-fed loads. Rated 400 V AC, 50/60 Hz, with a 10 kA short-circuit current rating (SCCR) per IEC 61008-1. The short-time delayed design (SIGRES function) provides selectivity upstream, letting a downstream fault clear before this device trips — critical for keeping the rest of the panel live during a ground fault on one branch. Depth of 70 mm matches the common SENTRON MCB/RCCB footprint — fits existing 70 mm deep distribution boards without re-glanding. The 72 mm width (4 MW) is one slot wider than a 3-pole MCB; plan the DIN-rail fill accordingly when replacing a 3-pole device. Supply can enter top or bottom; the SIGRES function remains active even in the switched-off state when fed from the top. Silicon-free construction — suitable for applications where silicone outgassing is prohibited (paint lines, potting stations).","metaTitle":"Siemens 5SV3346-4KK60 SENTRON RCCB, Type B, 63A, 30mA, 4-pol","metaDescription":"Siemens SENTRON 5SV3346-4KK60 RCCB, 4-pole, Type B, 63A, 30mA, 6mA DC, 400V AC, 10 kA SCCR, short-time delayed, DIN rail.
