That AC-3e rating means it's tested for switching three-phase induction motors — the kind driving pumps, fans, and conveyors out here in the grease — and can handle the inrush without welding contacts. The 12 V DC coil pulls in reliably across 0.7–1.25× Uc, so it'll hold on a nominal 12 V supply even if the battery or control transformer sags under load. ## Panel fit and wiring constraints One NC auxiliary contact is built in, and no additional auxiliary switch block can be added to this variant — if you need more feedback contacts, pick a different order code within the S00 frame.","metaTitle":"Siemens 3RT2016-1HA42 SIRIUS Power Contactor, 9 A AC-3e, 12","metaDescription":"Siemens SIRIUS 3RT2016-1HA42 power contactor, 9 A AC-3e/AC-3, 4 kW at 400 V, 12 V DC coil, 1 NC auxiliary contact, screw terminal, frame S00, RoHS compliant.
