Its AC-2 rating at 400 V is 4 kW, covering slip-ring motor switching; the AC-4 rating at 400 V is 8.5 A for reversing or inching duty. For resistive loads (AC-12) it carries 10 A. Wire range for main and auxiliary terminals accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid/stranded, plus AWG equivalents 2x (20 to 16), 2x (18 to 14), or 1x 12. That covers most control and small power circuits without lug adapters. For type 1 coordination (contactor may need replacement after fault), use gL/gG 35 A.","metaTitle":"Siemens 3RT1016-1HB42 SIRIUS Power Contactor, Size S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1016-1HB42 power contactor, size S00, 24 VDC coil, screw terminals, 45 mm wide, IP20 front, current production.
