The 24 V DC coil pulls in at 85% of rated voltage (0.85 x Us) and drops out at 10% (0.1 x Us), giving a clean margin for control voltage sag on a 24 VDC bus. Spring-loaded terminals on the main circuit accept 2x (0.25... 2.5 mm²) solid or stranded, so no ferrule crimp needed for the typical control-wire gauges. For a conveyor or pump start-stop application, that's a decade-plus of daily cycling before the armature wears. The 45 mm width and 114 mm depth fit a standard 35 mm DIN rail (DIN EN 50022) with screw or snap-on mounting, and side-by-side mounting is allowed with 6 mm clearance to adjacent devices for heat dissipation. ## Switching Ratings — What the Numbers Mean AC-3 at 400 V: 5.5 kW (the motor-starting duty that matters for induction motors up to 7.5 hp). AC-4 at 400 V: 8.5 A (for inching or plug-reverse applications where the contactor breaks stalled-rotor current). DC switching is limited: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V — the arc extinction in DC is harder, so these are the maximum make/break currents. For resistive loads (AC-12), the maximum operating current is 10 A. Coil inrush (closing power) and holding power are both 3.3 W DC — the solenoid is a DC economizer design, so the coil doesn't overheat in continuous duty. Spring-loaded terminals for the main circuit accept 2x (0.25... 2.5 mm²) or AWG 24...14 — strip length is standard 8–10 mm. Side-by-side mounting is allowed; no derating required for adjacent contactors at rated load. One instantaneous NO auxiliary contact is built in.","metaTitle":"Siemens 3RT1017-2BB48-0NA3 SIRIUS Power Contactor, S00, 24 V","metaDescription":"Siemens 3RT1017-2BB48-0NA3 SIRIUS power contactor, size S00, 24 VDC coil, 5.5 kW at 690 V AC-3, spring terminals, IP20, current production.
