The 24 V DC coil pulls 3.3 W to close and holds at the same 3.3 W — no extra holding-power budget needed. The front face carries IP20 finger-safe protection; the terminals are also IP20. Dimensions are 45 mm wide, 57.5 mm tall, and 114 mm deep — fits a standard S00 footprint. ## Ratings and coordination Main contacts are rated 10 A in AC-12 (resistive) duty. For motor loads, AC-2 at 400 V delivers 4 kW; AC-4 at 400 V is 8.5 A. The contactor carries pollution degree 3 and operates from -25 °C to +60 °C, with a maximum altitude of 2 000 m. Type 2 coordination requires a 20 A gL/gG fuse; type 1 coordination uses a 35 A gL/gG fuse. ## Auxiliary contacts and coil Includes 2 instantaneous auxiliary contacts (no NC main contacts). The auxiliary contacts are rated 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V. Coil pick-up is at 0.85 x rated voltage; drop-out is at 1.1 x rated voltage. Main circuit connections use solder pin connectors.","metaTitle":"Siemens 3RT1016-5BB44 SIRIUS Power Contactor, 24 V DC Coil,","metaDescription":"Siemens 3RT1016-5BB44 SIRIUS power contactor, 3-pole, size S00, 24 V DC coil, 4 kW at AC-2 400 V, 5.5 kW at 690 V.
