Rated for 5.5 kW at 690 V AC (AC-3 duty) and 4.5 kW at 500 V, this contactor handles typical three-phase induction motors up to those power levels. For DC switching, the auxiliary contacts are rated 10 A at 24 V DC and derate to 0.3 A at 220 V DC — a curve that reflects the arc-extinction challenge at higher DC voltages. ## Mounting and Integration — DIN Rail, Spring Terminals, Side Clearance The 45 mm width and 60 mm height fit the S00 footprint; depth is 114 mm including the spring-loaded terminals. Main circuit connections use spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded wire, or 2x (24 to 14 AWG). The spring-cage design eliminates the need for screw-torque checks during commissioning — strip to 8 mm, insert, and the clamp holds. ## Coordination and Protection — Fuse Ratings, Mechanical Endurance Coil power consumption is 3.3 W DC for both closing and holding — the SIRIUS DC coil design does not reduce holding power after pick-up, so the coil draws continuous 3.3 W whenever energized.","metaTitle":"Siemens 3RT1016-2BB44-3MA0 SIRIUS Power Contactor, S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1016-2BB44-3MA0 power contactor, size S00, 24 VDC coil, spring-loaded terminals, 5.5 kW at 690 V.
