It carries a 10 kA core-to-PG surge capacity and a 0.5 kA core-to-core rating, clamping transients on the AS-i bus line before they reach connected slaves or the master. Rated IP67, the module withstands washdown and high-humidity environments — suitable for food-and-bev lines, car wash tunnels, or outdoor conveyor sections where moisture ingress is a risk. The module does not require its own AS-Interface address — it sits transparently on the bus, clamping overvoltages without consuming a node slot or adding configuration overhead. The 3RK1901-1GA00 is a phased-out product. Siemens no longer manufactures this exact variant; the listing carries a note directing inquiries to sales for further information. ## Integration and Environmental Fit Dimensions of 25 mm depth, 45 mm width, and 80 mm height keep the module compact enough for crowded DIN-rail assemblies — it occupies roughly the same footprint as a single SIRIUS contactor of size S00. The overvoltage detection function is built in, but ground fault detection is not present — the module handles differential and common-mode surges on the AS-i pair only, not leakage-to-earth faults on the bus cable.","metaTitle":"Siemens 3RK1901-1GA00 AS-i Overvoltage Protection Module, IP","metaDescription":"Siemens 3RK1901-1GA00 AS-Interface overvoltage protection module.
