Screw-type terminals on the main circuit accept 2x (0.5...1.5 mm²) solid or 2x (0.75...2.5 mm²) stranded, with a maximum of 2x (0.75...4 mm²). Finger-safe IP20 protection on the front and terminals. ## Motor ratings and coordination For AC-3 motor switching at 400 V, the contactor is rated 3 kW; at 690 V it reaches 4 kW. AC-4 reversing duty at 400 V is rated 6.5 A — relevant for plugging or inching applications where the contactor breaks stalled rotor current. Type 1 coordination requires a 35 A gL/gG fuse; Type 2 coordination needs a 20 A gL/gG fuse. The coil draws 3.3 W holding power, same as pick-up — DC economizer is built in. Side-by-side mounting is permitted with 6 mm spacing to adjacent devices.","metaTitle":"Siemens 3RT1015-1BN41 SIRIUS S00 Power Contactor, 24 VDC Coi","metaDescription":"Siemens 3RT1015-1BN41 SIRIUS S00 power contactor, 24 VDC coil, 10 A AC-1 rating.
