LSiS GTK-12M Thermal Overload Relay 5-8A

The LSiS GTK-12M thermal overload relay is a precision-engineered component designed to provide robust protection for electrical motors in industrial environments. Operating within an adjustable current range of 5-8A, this device monitors electrical loads to prevent damage caused by overheating, overloads, or phase loss. Its compact design allows for seamless integration into control panels and automation systems, ensuring consistent performance and enhanced safety for critical machinery.

Advantages

This thermal overload relay offers exceptional reliability by reacting quickly to abnormal current conditions, thereby extending the lifespan of connected motors. The adjustable current setting provides flexibility for various motor configurations, allowing for precise calibration to match specific operational requirements. Its durable construction is built to withstand the rigors of industrial use, minimizing downtime and maintenance costs associated with motor failures.

Suitable for

• Industrial motor control centers
• Automation and control panels
• HVAC systems and pump controls
• Manufacturing machinery and conveyor systems

When it may not be suitable

This device is specifically designed for motor protection within the 5-8A range and is not suitable for applications requiring higher current ratings or protection for non-motorized electrical loads. It should not be used in environments exceeding the specified temperature or humidity ratings provided by the manufacturer.

Key specifications

• Adjustable current range: 5-8A
• Protection type: Thermal overload and phase failure
• Mounting: Direct contactor mounting or independent installation
• Device type: Thermal overload relay

How to use

The LSiS GTK-12M is typically installed directly onto a compatible contactor or mounted independently within an electrical enclosure. Once installed, the current range should be adjusted using the dial on the front of the device to match the full-load current rating of the motor being protected. Ensure all electrical connections are tightened to the specified torque to prevent overheating at the terminals. After installation, perform a test to verify that the relay trips correctly under simulated overload conditions.

What to consider before purchase

• Verify that the motor full-load current falls within the 5-8A range.
• Ensure compatibility with the existing contactor model.
• Check the environmental conditions of the installation site.
• Confirm that the relay meets the specific safety standards required for your application.

Usage recommendations

Regularly inspect the relay for signs of wear or loose connections and verify that the current setting remains calibrated to the motor's operational requirements to ensure continuous protection.
