## Long description

The LSiS GTK-12M thermal overload relay is a precision-engineered protection component designed to safeguard electric motors from damage caused by thermal overloads and phase failures. With an adjustable current range of 0.63-1A, this device offers flexible configuration to match the specific operational requirements of your motor, ensuring reliable performance in demanding industrial environments.
Advantages
This thermal overload relay stands out due to its robust construction and high sensitivity to abnormal current conditions. By monitoring the current flow, it effectively prevents motor burnout, thereby extending the lifespan of your electrical equipment and reducing downtime. Its compact design allows for easy integration into existing control panels, while the adjustable dial provides precise control over the protection threshold, making it a versatile solution for various motor protection needs.
Suitable for
Industrial automation systems
Electric motor protection in manufacturing machinery
HVAC control panels
Conveyor belt motor management
Pump and fan motor protection
When it may not be suitable
This device is not intended for use in circuits where the motor current exceeds the specified 0.63-1A range. It is also not suitable for protecting against short-circuit faults, as it is designed specifically for thermal overload protection and should be paired with appropriate short-circuit protection devices like fuses or circuit breakers.
Key specifications
Adjustable current range: 0.63-1A
Protection type: Thermal overload and phase failure
Compatibility: Designed for integration with contactors
Mounting: Standard DIN rail or direct contactor mounting
How to use
The relay is typically installed directly onto the output side of a compatible contactor. Once mounted, the current setting dial should be adjusted to match the full-load current rating of the motor being protected. Ensure all electrical connections are tightened to the manufacturer's torque specifications to prevent overheating at the terminals. After installation, the device can be tested using the integrated test function to verify that the trip mechanism is operational.
What to consider before purchase
Verify the full-load current rating of your motor falls within the 0.63-1A range
Ensure compatibility with your existing contactor model
Check the environmental conditions of the installation site
Confirm that additional short-circuit protection is present in the circuit
Usage recommendations
Regularly inspect the terminal connections for tightness and ensure the relay is free from dust or debris. Periodically verify the trip settings during scheduled maintenance to ensure continued protection of your motor assets.
