The AC-3 rating governs motor starting — this is the figure a panel builder sizes against. For fuse coordination, the evidence lists two protection levels: type 2 coordination requires a 20 A gL/gG NH fuse (3NA series), while type 1 allows up to 35 A. That distinction matters for selectivity studies: type 2 keeps the contactor serviceable after a fault, type 1 may sacrifice it. The DC magnet coil draws 0.8 W on closing and holds at 0.27 W — a low holding power that reduces heat inside a crowded enclosure. ## Integration notes Operating temperature range is -10 to +55 °C; storage from -25 to +70 °C. The auxiliary switch option is available as a product extension, so the same base contactor can be field-fitted with additional contacts without replacing the unit.","metaTitle":"Siemens 3RT7014-1AN21 Contactor, Size S00, 3-pole, 690 V","metaDescription":"Siemens 3RT7014-1AN21 Size S00 contactor, 3-pole, 690 V insulation, screw terminals, IP20, active production.
