It carries a 10 kA short-circuit current rating and is designed as short-time delayed, meaning it tolerates brief surge currents — up to 3 kA rated surge current resistance — without nuisance tripping, which matters when feeding loads with capacitive inrush or downstream surge suppressors. The 30 mA residual sensitivity and Type A waveform detection (AC sinusoidal plus pulsating DC fault currents) cover the majority of modern electronic loads — switched-mode power supplies, variable-speed drives, LED drivers — that generate pulsating DC leakage. Standard Type AC RCCBs may not trip on those waveforms; Type A is the baseline for commercial and light industrial panels today. The short-time delayed characteristic (letter K or short-time delayed designation) allows the device to ride through brief earth-fault current pulses up to 3 kA without tripping, which prevents coordination issues with surge protective devices or capacitor switching banks upstream. It is not a general-purpose instantaneous RCCB — fit it where you need selectivity against transient leakage. Rated 40 A at 230 V AC, this unit covers feeder circuits up to that continuous load. Mounts on DIN rail (REG profile) in any position, occupying 2 width units (36 mm). Installation depth is 70 mm — check enclosure depth clearance; the body projects 70 mm from the rail. Silicon-free construction is specified — relevant for environments where silicone outgassing can contaminate contacts or optics.","metaTitle":"Siemens 5SM3314-6KK01 SENTRON RCCB, 40 A, 30 mA, Type A, Sho","metaDescription":"Siemens 5SM3314-6KK01 SENTRON RCCB, 2-pole, Type A, short-time delayed, 40 A, 30 mA, 230 V AC. 10 kA SCCR.
