The adjustable 63-630 A range means one module spans a wide motor FLA band, reducing SKU count. The AC-3e maximum voltage of 1 000 V confirms it works in 690 V systems common in heavy industrial installations. The fastening method (contactor mounting or stand-alone) gives flexibility: bolt it onto the S10/S12 contactor for a compact assembly, or mount it separately on the panel backplate if the contactor is already crowded. The module carries a substance prohibition date of July 1, 2006, aligning with the original EU RoHS directive. No UL, CSA, or CE mark is explicitly listed in the evidence, but as a Siemens SIRIUS component it is typically designed for IEC markets. For compliance documentation (RoHS, REACH, manufacturer declarations), request them with your RFQ.","metaTitle":"Siemens 3RB2966-2WH2 SIRIUS Current Measuring Module, 63-630","metaDescription":"Siemens 3RB2966-2WH2 SIRIUS current measuring module, adjustable 63-630 A, NRND.
