The 110 VDC coil pulls 2.3 W on close and holds at 2.3 W — a constant-power DC coil, so no holding-current drop to worry about. Type 2 coordination (the standard for most industrial panels) requires a 20 A gL/gG fuse upstream; Type 1 coordination allows a 35 A fuse. Side-by-side mounting is permitted, which means no derating for zero-gap packing in a multi-contactor group. ## Coil and auxiliary circuit The coil includes a built-in varistor as the surge suppressor, which clips the inductive kickback when the DC coil de-energizes. That's important if the coil is driven by a PLC output or a solid-state relay — without the varistor, the flyback voltage can exceed the semiconductor's breakdown rating. The auxiliary contact ratings cover the usual control voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 110 V (the coil voltage itself).","metaTitle":"Siemens 3RT1017-2KF41 SIRIUS Power Contactor, Size S00, 110","metaDescription":"Siemens 3RT1017-2KF41 SIRIUS power contactor, Size S00. 110 VDC coil with varistor.
