It is rated for AC-3 duty at 5.5 kW at 400 V, with a 24 V DC coil, and comes in size S00 with spring-loaded terminals. The order code includes two factory-fitted 3RH2911-2DA20 auxiliary contact blocks, each providing 2NO+2NC contacts, mounted left and right. The part ships in reusable packaging of 80 pieces. For a pole-changing contactor, this rating applies to each winding configuration; the contactor must handle the inrush and the switched current for both speed settings. ## Deployment context The spring-loaded terminals reduce wiring time compared to screw terminals, especially in high-density panels where access is tight. The pole-changing function is typically used in applications like fans, pumps, or machine spindles that require two discrete operating speeds — the contactor switches the motor winding configuration, not just the power supply.","metaTitle":"Siemens 3RT2517-2BB48-0PT1-ZX95 SIRIUS Contactor, AC-3 5.5kW","metaDescription":"Siemens SIRIUS 3RT2517-2BB48-0PT1-ZX95 pole-changing contactor, AC-3 5.5kW at 400V, 24VDC coil, size S00, spring-loaded terminals, with 2x 3RH2911-2DA20 aux blocks (2NO+2NC).
