Siemens 3RT1016-1AB02 AC Solenoid Contactor Coil

Siemens SIRIUS 3RT1016-1AB02 is a three-pole AC-3 power contactor with a 24 V AC coil, designed for 50/60 Hz control circuits and intended for use with Siemens SIRIUS 3RT contactors in size S00. This compact unit switches inductive loads and small to mid-size motors in industrial control panels, rated up to 4 kW at 400 V in AC-3 duty, making it suitable for applications such as fans, pumps, conveyors, and machine tools. It features screw-terminal connections for straightforward wiring and an IP20 enclosure rating for panel mounting, with overall dimensions around 57.5 mm high, 45 mm wide, and 72 mm deep. The 24 V coil enables reliable energization from standard low-voltage control circuits, and the device is part of Siemens’ widely used SIRIUS family, offering proven compatibility with common control relays and optional auxiliary blocks to expand signaling and interlock functionality. This model’s combination of compact footprint, robust switching capability, and familiar Siemens design makes it a common choice in automation and motor-control installations where a 3-pole, 24 V coil contactor is required.
