Specification & Description

The Siemens 3RU1126-1FB0 is a thermal overload relay designed to provide efficient motor protection. This component is essential for safeguarding motors in industrial applications from potential damage due to overloads. With an adjustable response current range of 3.5 to 5 A, it ensures precise protection for motors by tripping in the event of an overload, thus preventing motor burnout and downtime.

Crafted for direct mounting onto contactors, the 3RU1126-1FB0 is part of the SIRIUS product family, renowned for reliability and performance. It features a compact design with dimensions of 96 mm in depth, 97 mm in height, and 45 mm in width, making it suitable for installations where space is at a premium.

The overload relay is equipped with three main poles for the current circuit and offers a finger-safe protection class of IP20, ensuring a high level of safety during operation. It is capable of withstanding impulse voltages up to 6 kV and operates within an ambient temperature range of -20 to +70°C, making it robust for challenging industrial environments.

Additionally, the 3RU1126-1FB0 includes one normally closed (NC) and one normally open (NO) auxiliary contact, providing flexibility for control circuit integrations. It is designed to be used with a size S0 contactor, and it conforms to the CLASS 10 trip class, which specifies a trip time of 2 to 10 seconds under overload conditions of 600% of the set current value.

This overload relay is suitable for a wide range of industrial applications, including manufacturing, processing, and automation systems, where motor protection is critical for operational efficiency and safety.
