The Siemens 3RU2116-1GB1 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 performance in industrial applications. With a size S00 footprint, it is compatible with similarly sized contactors, making it a versatile choice for various installations.
This overload relay is engineered to protect motors in the event of overload or phase failure, with an adjustable current setting range of 4.5 to 6.3 A, ensuring precise protection for motors according to their specific requirements. The class 10 protection ensures a rapid response to overload conditions, helping to prevent motor damage and prolonging the service life of the equipment.
The main circuit connection is facilitated through screw terminals, which offer a secure and durable connection for both the main and auxiliary circuits. The device also features manual and automatic reset functions, providing flexibility in control and resetting procedures.
Constructed to withstand challenging industrial environments, the 3RU2116-1GB1 can operate effectively within a wide temperature range from -40 to +70 °C and at installation altitudes up to 2000 metres above sea level. Its robust design includes a shock resistance in compliance with IEC 60068-2-27 standards and an insulation voltage rated at 690 V, with a surge voltage resistance of 6 kV.
The thermal overload relay also comes with integrated auxiliary contacts, one normally closed (NC) for contactor disconnection and one normally open (NO) for signalling a "Tripped" condition, enhancing its functionality in monitoring and control systems.
With its comprehensive protection features and durable construction, the Siemens 3RU2116-1GB1 is an essential component for safeguarding motors in a wide range of industrial applications.
