The Type B+ curve detects smooth DC fault currents plus AC and pulsed DC — critical for variable-speed drives, UPS systems, and PV inverters where standard AC-only RCCBs would be blind to a fault. The 30 mA trip threshold meets the IEC 61008-1 requirement for personal protection (additional protection against direct contact). ## Short-time delayed design and selectivity This RCCB is short-time delayed (S-type), meaning it withstands transient leakage currents without tripping — essential for selectivity in a distribution board where downstream RCCBs clear first. The short-circuit current rating is 10 kA, and per IEC 61008-1 the rated conditional short-circuit current is 0.8 kA. The maximum permissible series fuse short-circuit current is 100 A, which governs the upstream protection you pair it with. Depth is 70 mm, height 90 mm. Mounting position is unrestricted. Silicon-free construction suits coating-sensitive environments like automotive paint lines.","metaTitle":"Siemens 5SV3346-4KK14 SENTRON RCCB, 4P, 63A, 30mA, Type B+","metaDescription":"Siemens SENTRON 5SV3346-4KK14 RCCB, 4-pole, Type B+, 63 A, 30 mA, 400 V AC, short-time delayed.
