Siemens 3RQ3018-1AB00 Soft Starter

Siemens 3RQ3018-1AB00 is a compact output coupler for the Sirius 3RQ3 family that provides one changeover contact driven by a 24 V AC/DC coil. Housed in a slim module just 6.2 mm wide with screw-terminal connections, it is designed for control-panel installations where a small, isolated relay interface is required to connect control circuits to external loads. The unit carries a rated thermal current of 6 A and conforms to IP20 protection, making it suitable for interior industrial cabinets and automation panels. As part of Siemens' Sirius 3RQ3 relay accessories, the 3RQ3018-1AB00 serves as a lightweight, space-efficient means to couple a 24 V control signal to an auxiliary circuit or signaling device, enabling safe, compact interface between supervisory controls and peripheral equipment in soft-start and signaling applications.
