The AC-3 motor-switching rating at 400 V is 3 A, which translates to roughly 1.5 kW for a standard induction motor — sized for small pumps, fans, or conveyor drives. For resistive loads (AC-1), the contactor carries 10 A at 400 V. The DC coil draws 3.3 W holding power, which is low enough to keep the control transformer small. ## Integration notes The IP20 front and IP20 terminal protection require the contactor to be installed inside a panel or enclosure. For type 2 coordination (no weld under fault), use a 20 A gL/gG fuse upstream; for type 1 coordination, a 35 A fuse is allowed.","metaTitle":"Siemens 3RT1016-1BF42 SIRIUS Power Contactor, S00, 110 V DC","metaDescription":"Siemens 3RT1016-1BF42 SIRIUS power contactor, size S00, 110 V DC coil, 45 mm width, screw terminals, IP20 front.
