Specification & Description

The Siemens 3RU2126-4CB0 is a high-quality overload relay from the renowned SIRIUS series, designed to provide reliable motor protection. This component is engineered to safeguard motors by monitoring and breaking the circuit in the event of an overload, thus preventing potential damage to your machinery.

Crafted for use in a wide range of industrial applications, the 3RU2126-4CB0 features a thermal overload relay with an adjustable current response value, making it suitable for motors with a current range of 17 to 22 amperes. Its compatibility with size S0 contactors allows for seamless integration into existing setups, ensuring a straightforward installation process.

The overload relay is equipped with both 1NC (normally closed) and 1NO (normally open) contacts, providing flexibility for various control circuit configurations. The screw-type terminals ensure a secure and reliable connection for both the main and auxiliary circuits.

With a compact design measuring 45 x 85 x 85 mm, this overload relay is an efficient space-saving solution for your control panels. It operates effectively within a voltage rating of up to 690 V ac, and its robust construction is capable of withstanding the rigours of industrial environments.

The 3RU2126-4CB0 is characterised by its Class 10 trip class, which denotes a quick response to overloads, typically within 10 seconds, to provide optimal protection for your motors. Additionally, the manual-automatic-reset feature offers convenience in resetting the relay after a trip event.

This overload relay is a testament to Siemens' commitment to quality and reliability, making it an essential component for maintaining the operational integrity of your motor-driven systems.
