## Summary description

The LSiS GTK-12M thermal overload relay is a reliable protection device designed for electric motors with an adjustable current range of 2.5-4A. It provides essential protection against motor overheating caused by overloads or phase failures. This compact component is ideal for industrial control panels and motor starter applications, ensuring operational safety and preventing equipment damage in various electrical systems.

## Long description

The LSiS GTK-12M thermal overload relay is a precision-engineered protection device specifically designed to safeguard electric motors from damage caused by thermal stress. With an adjustable current range of 2.5-4A, this relay offers flexible configuration to match the specific operational requirements of your motor, ensuring reliable performance in demanding industrial environments. By monitoring current flow, the device effectively detects overload conditions and phase failures, triggering a protective disconnect to prevent overheating and potential motor burnout.
Advantages
This thermal overload relay stands out due to its robust construction and high reliability in continuous operation. Its compact design allows for efficient space utilization within control cabinets and motor starter assemblies. The adjustable current setting provides versatility, allowing users to fine-tune protection parameters to suit specific motor characteristics. Furthermore, the device is built to withstand harsh industrial conditions, ensuring long-term stability and reducing the risk of unexpected equipment downtime.
Suitable for
Industrial motor control centers
Electric motor starter applications
Protection of pumps and ventilation systems
Automation systems requiring reliable overload monitoring
This device may not be suitable for applications requiring protection against short-circuit currents, as it is specifically designed for thermal overload and phase failure protection. It should not be used in environments where the ambient temperature exceeds the manufacturer's specified operating range or in highly corrosive atmospheres without appropriate enclosure protection.
Key specifications
Current adjustment range: 2.5-4A
Protection type: Thermal overload and phase failure
Mounting: Compatible with standard motor starter configurations
Application: Electric motor protection
Installation of the LSiS GTK-12M should be performed by qualified personnel in accordance with local electrical regulations. The relay is typically mounted directly onto a compatible contactor. Once installed, the current dial must be set to the rated full-load current of the motor being protected. After the initial setup, the device operates automatically, monitoring the circuit and tripping the contactor if an overload condition is detected.
What to consider before purchase
Verify that the motor's full-load current falls within the 2.5-4A range
Ensure compatibility with your existing contactor model
Confirm the environmental conditions of the installation site
For optimal performance and safety, ensure that all electrical connections are tightened to the specified torque values and that the relay is periodically inspected for signs of wear or environmental damage.
