## Long description

The LS GTK-12M thermal overload relay is a precision-engineered component designed to provide reliable protection for electric motors against overloads and phase failures. With an adjustable current range of 0.4 to 0.63A, this relay offers accurate monitoring to prevent damage to electrical equipment in industrial environments. Its robust construction ensures consistent performance and operational safety, making it an essential element for maintaining the integrity of complex electrical circuits and automation systems.
Advantages
This thermal overload relay stands out due to its high level of precision in current monitoring, which allows for fine-tuned protection tailored to specific motor requirements. The device is built to withstand demanding industrial conditions, ensuring long-term durability and stability. By effectively detecting overloads and phase imbalances, it helps prevent costly equipment downtime and extends the service life of connected machinery. Its compact design facilitates easy integration into existing control panels and electrical cabinets.
Suitable for
Industrial motor control centers
Automation and control systems
HVAC equipment protection
Conveyor belt motor management
Pump and fan control circuits
When it may not be suitable
This device is not intended for use in circuits where the motor current falls outside the specified 0.4 to 0.63A range. It is also not suitable for applications requiring short-circuit protection, as it is specifically designed for thermal overload and phase failure monitoring rather than instantaneous fault interruption.
Key specifications
Adjustable current range: 0.4 - 0.63A
Protection type: Thermal overload and phase failure
Application: Motor protection
Design: Compact industrial relay
How to use
The relay should be installed directly onto the corresponding contactor in the electrical control cabinet. Once mounted, the current setting dial must be adjusted to match the full-load current rating of the motor being protected. After installation, ensure all terminal connections are tightened securely to prevent overheating. 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 the full-load current rating of your motor
Ensure compatibility with the existing contactor model
Check the environmental conditions of the installation site
Confirm the need for manual or automatic reset functionality
Usage recommendations
Regularly inspect the relay for signs of wear and ensure that the current setting remains calibrated to the motor's specifications. Periodically test the trip function to verify that the protection mechanism is fully operational.
