The 10 A rating at 24 V and 230 V tells you this contactor handles moderate current in both low-voltage DC and standard AC line applications. At 400 V it's rated 3 A — useful for three-phase motor circuits at that voltage. The mechanical life of 30 million operations and AC switching rate of 10 000 cycles per hour (1 000 per hour at AC-1 maximum) mean it's built for high-cycle applications like packaging lines or conveyor sorters. Arcing time runs 10 to 15 ms, DC switching time 7 to 13 ms — numbers to check if you're timing interlock sequences. The coil picks up at 0.8 of rated voltage and drops out at 1.1 of full-scale value — standard for 24 V DC coils, meaning it holds in reliably down to about 19.2 V and releases above 26.4 V. ## Mounting and wiring flexibility Wire sizes accepted: 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², or 2x 4 mm² solid or stranded — covers most panel wiring up to 4 mm².","metaTitle":"Siemens 3RT2517-1BB40 SIRIUS Contactor, Size S00, 24 V Coil,","metaDescription":"Siemens SIRIUS 3RT2517-1BB40 contactor, Size S00, 24 V DC coil, screw terminals, 10 A rated at 24 V / 230 V.
