Coil pulls 24 VDC; the contactor drops out between 20 and 25 ms on DC, arcing clears in 10 to 15 ms. AC-3 at 400 V is the real-world motor rating: 22 kW covers a 30 hp class motor on a 400 V line. Maximum switching frequency at AC-3 is 1 000 operations per hour; at AC-4 it drops to 300 per hour because the arc energy is higher. The auxiliary contacts handle 10 A at 24 VDC, 6 A at 230 V, tapering to 0.3 A at 220 VDC — enough for a PLC input or a holding relay, but not a second contactor coil without a suppression network. The S2 frame is 55 mm wide, 112 mm tall, 130 mm deep — fits a standard 200 mm deep enclosure with room for the gland plate.","metaTitle":"Siemens 3RT1035-1BB40-ZX95 SIRIUS Power Contactor, 22 kW AC-","metaDescription":"Siemens SIRIUS 3RT1035-1BB40-ZX95 Size S2 power contactor. 22 kW AC-3 at 400 V, 35 A AC-4, 24 VDC coil.
