The IP20 finger-safe enclosure protects personnel during panel access. ## Switching Capacity and Motor Duty Switching capacity varies by voltage: at 24 V it handles 10 A, at 60 V it handles 2 A, at 110 V it handles 1 A, and at 220 V it handles 0.3 A — these are the DC-12/DC-13 style ratings for resistive and inductive DC loads. For AC motor duty, the contactor is rated at 4.5 kW at 400 V and 5.5 kW at 690 V in AC-3 utilization category (standard squirrel-cage motor starting). In AC-2 duty (slip-ring motors) at 400 V it's rated 4 kW. For AC-4 duty (plugging/inching) at 400 V it carries 8.5 A. The AC-12 maximum operating current is 10 A for resistive loads. These values guide the upstream protection device selection. The 45 mm wide, 60 mm tall, 73 mm deep S00 frame allows side-by-side mounting without derating. The part carries the Siemens SIRIUS brand and is referenced as Q per DIN EN 81346-2.","metaTitle":"Siemens 3RT1016-2BW42 SIRIUS Power Contactor, S00, 24 VDC Co","metaDescription":"Siemens SIRIUS 3RT1016-2BW42 power contactor, Size S00, 24 VDC coil, spring-loaded terminals.
