It's built for switching motor loads in control panels: rated 4 kW at 400 V in AC-2 duty (slip-ring motors, moderate inrush) and 8.5 A at 400 V in AC-4 (plugging, inching, reversing). The 24 VDC coil draws 2.3 W to pull in and holds at the same power — no separate hold-in economizer needed, which simplifies the control transformer sizing. ## Coil ratings and switching capacity The DC coil is rated for continuous duty across the operating range of -25 °C to +60 °C. Switching capacity at 24 VDC is 10 A; at 60 VDC it drops to 2 A, at 110 VDC to 1 A, and at 220 VDC to 0.3 A — the inductive load curve matters here, so don't expect the 24 A figure to hold at higher voltages. For the main power circuit, the screw-type terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) solid or stranded — plenty of room for motor power leads up to 4 kW. Type 1 coordination requires a 35 A gL/gG fuse upstream; Type 2 coordination needs a 20 A gL/gG fuse. That's the maximum short-circuit protection the contactor can ride through without welding its main contacts — size your branch circuit protection accordingly. Pollution degree 3 (industrial environment, conductive dust or condensation) is the rated environment — standard for most factory-floor control panels.","metaTitle":"Siemens 3RT1016-1HB41 SIRIUS Power Contactor, Size S00, 24 V","metaDescription":"Siemens 3RT1016-1HB41 SIRIUS power contactor, size S00, 24 VDC coil, 10 A at 24 VDC, AC-2 4 kW at 400 V.
