It carries a 63 A ampacity and is rated for 690 V insulation at pollution degree 3. Connection is via screw-type terminals accepting solid conductors 1x (2.5... 16 mm²) or stranded up to 25 mm². ## Lifecycle reality — phased out with a direct successor This part is a phased-out product. The official successor is the SIRIUS 3RV2925-5AB for use with 3RA6 contactor assemblies; for standalone breaker applications the preferred replacement is 3RV2925-5EB. Both maintain the same 45 mm width, 63 A ampacity, and screw-terminal connection pattern, so a panel swap should be a straight drop-in on the DIN rail.","metaTitle":"Siemens 3RV1925-5AB SIRIUS 3-Phase Supply Terminal, 63 A","metaDescription":"Siemens 3RV1925-5AB SIRIUS 3-phase supply terminal, 63 A ampacity, 690 V insulation.
