## Summary description

The LS GTK-12M thermal overload relay is designed for reliable motor protection against overloads and phase failures. With an adjustable current range of 1.6 to 2.5A, this device ensures operational safety in industrial electrical systems. It is engineered for seamless integration with contactors, providing precise thermal monitoring and preventing equipment damage in various automation applications.

## Long description

The LS GTK-12M thermal overload relay is a high-quality protective device engineered to safeguard electric motors from damage caused by overloads and phase failures. Designed for industrial environments, this relay provides precise thermal monitoring within an adjustable current range of 1.6 to 2.5A, ensuring that your electrical systems remain operational and protected against unexpected surges or mechanical stress.
Advantages
This thermal overload relay offers exceptional reliability by providing a consistent response to thermal conditions, which helps in extending the service life of connected motors. Its compact design allows for efficient space utilization within control panels, while the adjustable current setting provides the flexibility needed to calibrate the device precisely to the specific requirements of your motor. The integration process is straightforward, allowing for seamless mounting directly onto compatible contactors, which reduces installation time and complexity in automation setups.
Suitable for
Industrial motor control centers
Automation and conveyor systems
HVAC equipment and ventilation fans
Pumping stations and fluid management systems
This device may not be suitable for applications requiring protection against short-circuit currents, as it is specifically designed for thermal overload monitoring. It should not be used in environments where the ambient temperature significantly exceeds the manufacturer's specified operating range or in systems where the motor current falls outside the 1.6 to 2.5A adjustment range.
Key specifications
Current adjustment range: 1.6 - 2.5A
Function: Thermal overload and phase failure protection
Compatibility: Designed for integration with LS contactors
Mounting type: Direct contactor mounting
To use the LS GTK-12M, mount the relay directly onto the corresponding contactor terminal. Once installed, use the adjustment dial on the front of the unit to set the current value according to the rated full-load current of your motor. Ensure that all electrical connections are tightened securely to prevent overheating at the terminals. The device features a manual or automatic reset function, which can be configured based on your specific operational requirements.
What to consider before purchase
Verify that the motor's full-load current falls within the 1.6 - 2.5A range
Ensure compatibility with your existing contactor model
Check the environmental conditions of the installation site
Usage recommendations: Regularly inspect the relay for any signs of physical damage or discoloration. It is recommended to perform a functional test during scheduled maintenance to ensure the trip mechanism operates correctly under simulated overload conditions.
