Type A is the right choice when the downstream loads include single-phase rectifiers, switched-mode power supplies, or VFDs with minimal DC-link filtering. Standard type AC RCCBs can blind to pulsating DC faults; type A catches them. If your line has 3-phase drives with active front ends or EV chargers, you need type B or B+ — but for general industrial and commercial panels with VFDs below about 7.5 kW, type A covers the majority of installations. ## Panel integration — DIN-rail footprint Packaging dimensions are 78 x 97 x 85 mm — standard 4-module width for a 4-pole RCCB on a 35 mm DIN rail. The 125 A rating means the incoming cable section will be at least 35 mm² Cu; verify the tunnel terminal accepts that size before wiring. Spring-cage or screw terminals? Not stated in the evidence — confirm termination type on the physical unit or the full datasheet before panel layout.","metaTitle":"Siemens 5SV3345-6 RCCB, 125A 30mA Type A, 400V","metaDescription":"Siemens 5SV3345-6 RCCB, 4-pole type A, 125 A rated current, 30 mA residual sensitivity, 400 VAC.
