That 22 kW at 690 V tells you it handles higher-voltage motors without stepping up a frame size. Dimensions are 45 mm wide, 57.5 mm high, and 73 mm deep — the S00 footprint is the smallest SIRIUS contactor frame, saving DIN-rail space in dense panels. Maximum switching frequency at AC-3 duty is 750 cycles per hour (AC-3e same), and at DC it's 10,000 cycles per hour — that 10k figure is for DC control circuits, not main contacts, so keep that distinction when sizing for high-cycling applications. Coil draws 6 A at 24 V rated value, 1 A at 110 V, 0.3 A at 220 V, 10 A at 230 V, 3 A at 400 V, and 1 A at 690 V. The 10 A at 230 V is the inrush — the holding current is lower, but your control transformer needs to handle that peak.","metaTitle":"Siemens 3RT6018-1BM41 SIRIUS Contactor, 7.5 kW at 230 V","metaDescription":"Siemens 3RT6018-1BM41 SIRIUS power contactor, Size S00, 7.5 kW at 230 V (60 °C), 13 kW at 400 V.
