## Long description

The Siemens 3RU2116-1DB0 is a high-quality thermal overload relay engineered to provide robust protection for electric motors in industrial environments. Designed specifically for size S00 contactors, this device monitors current flow to prevent damage caused by thermal overload or phase loss, thereby extending the service life of connected equipment and ensuring consistent operational reliability.
Advantages
This thermal overload relay offers precise current adjustment within the range of 2.2 to 3.2A, allowing for accurate calibration to specific motor requirements. Its compact design facilitates easy integration into existing control cabinets, while the integrated reset function and trip class support reliable performance under varying load conditions. The robust construction ensures durability in demanding electrical systems, minimizing downtime and maintenance needs.
Suitable for
Industrial motor control circuits
Protection of three-phase induction motors
Integration with S00 size contactors
Systems requiring phase failure protection
When it may not be suitable
This device is not intended for use with motors requiring current settings outside the 2.2 to 3.2A range. It is also not suitable for applications requiring electronic overload protection with advanced communication features or for use with contactors of sizes other than S00 without appropriate mounting accessories.
Key specifications
Current setting range: 2.2 - 3.2A
Size: S00
Protection type: Thermal overload and phase failure
Mounting: Direct mounting to contactor
How to use
The relay is designed for direct mounting onto the corresponding S00 contactor. Once physically attached, the main power cables are connected to the terminals. The desired current value should be set using the adjustment dial on the front of the device, matching the full-load current rating of the motor. After installation, the device can be set to manual or automatic reset mode depending on the specific operational requirements of the system.
What to consider before purchase
Verify that the motor full-load current falls within the 2.2 - 3.2A range
Ensure compatibility with size S00 contactors
Check the environmental conditions of the installation site
Usage recommendations
Always ensure the power supply is disconnected before installing or adjusting the relay. Regularly inspect the terminals for tightness and verify that the current setting matches the motor nameplate data to ensure optimal protection.
