The AC-4 rating at 400 V is 8.5 A — that's the inching/plugging duty cycle rating, lower than AC-3 because of the higher switching stress. For resistive loads (AC-1), the contactor is rated 20 A at 400 V, but the AC-2 rating at 400 V is 4 kW — that covers wound-rotor motor duty where the starting current is controlled. The auxiliary contact ratings span 10 A at 24 V down to 0.3 A at 220 V — useful for interlocking or PLC input circuits at lower voltages. The built-in varistor surge suppressor protects the coil from voltage spikes; no external suppressor module needed for basic applications. Main and auxiliary/control circuits use screw-type terminals. Wire sizes accepted: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded. For AWG: 2x (20 to 16), 2x (18 to 14), or 1x 12. The RoHS compliance date is July 1, 2006, so it meets the original EU RoHS directive.","metaTitle":"Siemens 3RT1016-1KB41 SIRIUS Power Contactor, 24 VDC, 10 A A","metaDescription":"Siemens 3RT1016-1KB41 SIRIUS power contactor, size S00, 24 VDC coil, 10 A AC-3 at 400 V, screw terminals, IP20 front, snap-on DIN rail.
