## Long description

The Siemens 3RU2116-1BB0 thermal overload relay is a precision-engineered component designed to provide robust protection for electric motors in industrial environments. With a specific current setting range of 1.4 to 2A and a compact S00 frame size, this device is essential for maintaining the integrity of electrical systems by detecting and responding to thermal overloads and phase failures before damage occurs.
Advantages
This thermal overload relay offers exceptional reliability and ease of integration into existing automation setups. Its compact design allows for space-saving installation within control cabinets, while the direct mounting capability ensures a secure and efficient connection to compatible contactors. By providing accurate monitoring of motor currents, it effectively prevents overheating and extends the operational lifespan of connected machinery, contributing to overall system stability and reduced maintenance requirements.
Suitable for
Industrial motor protection
Automation and control systems
Direct mounting to contactors
Monitoring electrical circuits for phase loss
This device may not be suitable for applications requiring current ranges outside of the 1.4 to 2A specification. It is also not intended for use in environments where electronic overload protection or specific communication features are required, as this is a purely thermal-mechanical protection device.
Key specifications
Current setting range: 1.4 - 2A
Size: S00
Protection type: Thermal overload and phase failure
Mounting: Direct mounting to contactor
To use the Siemens 3RU2116-1BB0, first ensure the power supply is disconnected. Mount the relay directly onto the corresponding contactor using the integrated connection pins. Once installed, adjust the current setting dial to the rated current of the motor being protected. After wiring the control and main circuits, the device is ready to monitor the motor and will automatically trip the contactor if an overload condition is detected.
What to consider before purchase
Verify the motor's full-load current matches the 1.4 - 2A range
Ensure compatibility with S00 size contactors
Check environmental conditions for installation suitability
Usage recommendations
Regularly inspect the relay for signs of wear and perform periodic testing of the trip mechanism to ensure continued operational safety and reliability in your electrical system.
