The Siemens 3RU2126-4BC0 is a thermal overload relay designed to provide efficient motor protection. This component is part of the SIRIUS product family, renowned for its reliability and versatility in industrial applications. With a size S0 footprint, it is engineered to seamlessly integrate with contactors of the same size, ensuring a compact and efficient assembly.
This overload relay is adjustable for currents ranging from 14 to 20 A, making it suitable for a variety of motor sizes and applications. It features a class 10 tripping characteristic, which means it will trip in 10 seconds or less if the current exceeds 600% of its rated value, providing quick response to prevent motor damage due to overload conditions.
The main and auxiliary circuits of the 3RU2126-4BC0 utilise spring-type terminals, which facilitate a secure and maintenance-free electrical connection, enhancing the reliability of the installation. The manual-automatic-reset function allows for easy restoration of operation after a trip event.
Constructed to withstand challenging industrial environments, the relay operates effectively within a temperature range of -40 to +70°C and at altitudes up to 2000 metres above sea level. It also boasts an insulation voltage rating of 690V and a surge voltage resistance of 6kV, ensuring robust performance in electrical demanding situations.
The 3RU2126-4BC0 is designed with safety in mind, featuring finger-safe terminals and a protection class of IP20, which guards against the ingress of solid objects and enhances the safety of personnel during installation and maintenance.
This overload relay is a testament to Siemens' commitment to quality and innovation, providing a dependable solution for motor protection in a wide range of industrial applications.
