It is designed for electro-mobility applications — EV charging infrastructure — where DC fault currents from onboard chargers can blind standard AC-only RCDs. The 6 mA DC component (SIGRES function) ensures the device detects smooth DC residual currents up to 6 mA that would otherwise saturate a Type A core and prevent tripping on an AC fault. 30 mA sensitivity for personnel protection. Type A detects AC sinusoidal and pulsating DC residual currents. 6 mA DC detection (SIGRES) covers smooth DC faults for EVSE. This is the rated conditional short-circuit current per IEC 61008-1, verified with a 100 A gG series fuse upstream. For installations with higher prospective fault current, an upstream MCB or fuse with lower breaking capacity must coordinate. Short-time delayed design withstands transient leakage currents without nuisance tripping. Snap-on DIN rail (REG) mounting. Depth 70 mm, installation depth 70 mm.","metaTitle":"Siemens 5SV3344-6KK60 SENTRON RCCB, 4-pole, 40A, 30mA, 400V","metaDescription":"Siemens SENTRON 5SV3344-6KK60 RCCB, 4-pole Type A, 40A rated, 30mA sensitivity, 6mA DC, 400V AC.
