The AC-12 rating of 10 A is the resistive load limit — think heaters or incandescent lamps, not motors. For motor duty, the contactor is rated 4 kW at 400 V in AC-2 (slip-ring motors) and 8.5 A at 400 V in AC-4 (plugging/inching). Coil consumption is 3.3 W both closing and holding, so the DC supply sees a constant draw — no inrush spike. The coil pickup voltage is 85% of rated (20.4 VDC) and the dropout is 1.1 times rated (26.4 VDC), meaning it holds in through a sagging bus but drops cleanly when the control signal goes away. ## Where it goes in the panel Spring-loaded terminals accept 2x (0.25... 2.5 mm²) solid or stranded, or 2x (24... 14 AWG). No screwdriver needed for the main circuit — strip to 8 mm, push in. The auxiliary terminals are also IP20 finger-safe, so the contactor can sit near the front of the enclosure without shock-risk covers.","metaTitle":"Siemens SIRIUS 3RT1016-2BB42-ZW95 Power Contactor, S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1016-2BB42-ZW95 power contactor, size S00, 24 VDC coil, 10 A AC-12 rated, spring-loaded terminals, DIN rail mount.
