The Siemens 3RU1116-1AC1 is a thermal overload relay designed to provide efficient protection for motors in the event of an overload or phase failure. This component is part of the SIRIUS product family and is suitable for a size S00 contactor setup. It features a current adjustment range of 1.1 to 1.6 A, ensuring precise protection for a variety of motor sizes within this range.
Crafted with a focus on reliability and durability, the 3RU1116-1AC1 is equipped with a Cage Clamp connection for both the main and auxiliary circuits, facilitating a secure and maintenance-free connection that is resistant to vibration. The relay is also designed for stand-alone installation, with a compact form factor measuring 45 mm in width, 92 mm in height, and 78 mm in depth, allowing for efficient use of space inside control cabinets.
The overload relay operates with a trip class of 10, which ensures a quick response to overloads, typically within 10 seconds, to prevent motor damage. It is also rated for an impulse voltage resistance of 6 kV and offers a finger-safe design to enhance safety during installation and maintenance.
With an ambient operating temperature range of -20 to +70°C and capable of withstanding up to 100% relative humidity during operation, the 3RU1116-1AC1 is robust and suitable for challenging industrial environments. Additionally, it has been designed to be shock-resistant, withstanding impacts of 8g/10 ms, and can be installed at altitudes up to 2000 meters above sea level without derating.
The 3RU1116-1AC1 is a testament to Siemens' commitment to quality and innovation in motor control and protection, making it an essential component for a wide range of industrial applications.
