Siemens is a global powerhouse in industrial automation and electrification, present in over 190 countries. Their product portfolio is the most extensive on the market, covering everything from power distribution and control to digital factory solutions. For the electrical engineer, Siemens offers a comprehensive range of industrial control components: power contactors and auxiliary contactors for motor switching, SIRIUS compact starters and high-performance static starters, thermal overload relays, programmable safety relays (MSS series), function relays, and limit switches. For control and signaling, they provide high-quality pushbuttons and indicator lamps, alongside excellent motor protection circuit breakers. Siemens also leads in power generation technology, both from renewable and fossil sources, and is a key player in intelligent infrastructure and sustainable mobility.

These components are fundamental in building automation systems, industrial control panels, motor control centers (MCCs), and power distribution boards. They are deployed across manufacturing plants, energy generation facilities, building management systems, and process industries. The SIRIUS product line, for example, is specifically designed for integration into modern automation architectures, ensuring reliable switching and protection for motors and other loads in harsh industrial environments.

Key subcategories within the Siemens industrial control range include power contactors (e.g., 3RT2 series), auxiliary contactors (3RH2 series), and motor protection circuit breakers (3RV2 series). The SIRIUS 3RA6 compact starters combine a contactor, overload relay, and circuit breaker in a single device. The 3RU2 thermal overload relays and 3RK3 MSS safety relays are also critical. Article codes typically follow a pattern like 3RT2016-1BB42, where '3RT' indicates the product family (contactor), '2' the size, and subsequent digits specify coil voltage, auxiliary contacts, and other features.

At Electric Automation Network, we provide genuine Siemens components with full technical documentation and real-time pricing. Our team of specialized engineers offers personalized support for product selection and application. We ensure express worldwide shipping, so you can get the critical Siemens parts you need, when you need them, minimizing downtime and keeping your projects on schedule.
