The 45 mm width and snap-on mounting onto 35 mm DIN rail (DIN EN 50022) mean it fits a standard 45 mm slot in any control panel. For motor duty, the AC-4 rating at 400 V is 8.5 A — that's the current it can switch during inching or plug reversing, the hardest thermal cycle for a contactor. The AC-2 rating at 400 V is 4 kW, covering slip-ring motor starting. For resistive or general-purpose loads, AC-12 operating current is 10 A. The coil holds at 48 V, 50/60 Hz (rated values 0.8 to 1.1 at 50 Hz, 0.85 to 1.1 at 60 Hz). Operating temperature range is -25 to +60 °C, and altitude is rated up to 2 000 m.","metaTitle":"Siemens 3RT1016-2AH02 SIRIUS power contactor, 45 mm, spring","metaDescription":"Siemens 3RT1016-2AH02 SIRIUS power contactor, size S00, 45 mm width, spring-loaded terminals, AC-4 8.5 A at 400 V.
