For AC-4 duty (plugging, inching) at 400 V, the maximum operational current is 8.5 A — the rating that governs reversing or jogging applications. The AC-12 maximum current of 10 A covers resistive loads like heaters or lighting banks. Pollution degree 3 rating means it tolerates conductive dust and humidity typical of industrial enclosures not kept at climate-controlled conditions. Spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded wire, or 2x (24 to 14 AWG) for both main and auxiliary circuits. For Type 1 coordination (contactor may need replacement after a fault), the fuse rating is gL/gG 35 A. The built-in varistor surge suppressor on the coil handles voltage spikes from the DC switching — no external suppressor needed for most applications.","metaTitle":"Siemens 3RT1017-2KF42 SIRIUS Power Contactor, S00, 110 VDC,","metaDescription":"Siemens 3RT1017-2KF42 SIRIUS power contactor, size S00, 110 VDC coil, spring-loaded terminals, 5.5 kW at 400 V AC-2, IP20 front.
