The Type B characteristic means it detects smooth DC residual currents in addition to AC and pulsed DC — critical for variable-speed drives, UPS systems, and PV inverters that can generate DC fault currents a standard Type A or AC device would miss. The short-time delayed (S-type) selectivity prevents nuisance tripping when downstream devices clear a fault first, making it suitable for sub-distribution boards feeding multiple circuits. The 30 mA sensitivity (IΔn) provides personal protection against direct contact; at 63 A continuous rating, it handles the full load of a submain feeding a workshop or a small production line. The 70 mm installation depth matches standard distribution board clearances. Supply can be fed from top or bottom; the SIGRES function (a Siemens feature) keeps the device powered for testing even in the switched-off state when fed from the top.","metaTitle":"Siemens 5SV3326-4 SENTRON RCCB, Type B, 63A, 30mA, 2-Pole","metaDescription":"Siemens SENTRON 5SV3326-4 Type B RCCB, 63A rated, 30mA trip, 2-pole, short-time delayed. 10 kA SCCR.
