3RF2150-2AA04 SIEMENS

The 3RF2150-2AA04 is a solid-state relay (SSR) from Siemens, designed for single-phase switching applications. This compact SSR boasts an overall width of just 22.5 mm, making it suitable for installations where space is limited. It is capable of switching AC loads ranging from 48 to 460 volts, with a continuous current rating of 50 amps. The relay is controlled by a 24 V DC signal, offering compatibility with various control systems. The utilization of spring-type terminals ensures a secure and vibration-resistant connection, simplifying installation and maintenance. Solid-state relays offer several advantages over electromechanical relays, including faster switching speeds, longer lifespan, and silent operation. The 3RF21 series is known for its reliability and performance in demanding industrial environments. This particular model is well-suited for applications such as resistive load control, motor starting, and lighting control. Its robust design and high current capacity make it a versatile solution for a wide range of switching needs. Furthermore, the SSR's inherent lack of moving parts contributes to a significant reduction in wear and tear, resulting in increased operational longevity.
