The short-time delayed design (IEC 61008-1 rated 0.8 kA) introduces a deliberate trip delay, giving downstream MCBs or fuses time to clear a fault first. This selectivity is critical in multi-level distribution where you want the branch breaker to open, not the main RCCB. ## Panel integration and environmental limits Silicon-free construction suits environments where silicone outgassing can contaminate contacts or optics. Overvoltage Category III means it is rated for fixed-installation distribution level, not for downstream equipment-level protection. ## Power loss and supplementary devices Supply voltage for the test circuit is 70 V minimum, with the supply cord position at top or bottom (top preferred for SIGRES function to remain active in switched-off state).","metaTitle":"Siemens SENTRON 5SV3342-4KK14 RCCB, 4P, 25 A, 30 mA, Type B+","metaDescription":"Siemens SENTRON 5SV3342-4KK14 RCCB, 4-pole, Type B+, short-time delayed, 25 A, 30 mA, 400 V AC.
