Suitable for
Industrial motor control centers
Commercial HVAC systems
Conveyor belt motor protection
Pump and fan motor applications
General electrical automation systems
This device may not be suitable for applications requiring protection against short-circuit currents, as it is designed specifically for thermal overload and phase loss 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 protective enclosures.
Key specifications
Adjustable current range: 4-6A
Protection type: Thermal overload and phase loss
Compatibility: Designed for integration with motor starters
Design: Compact and durable housing
To use the LSiS GTK-12M, mount the device directly onto the compatible contactor or use a separate mounting bracket if required by your panel layout. Connect the motor supply cables to the output terminals and ensure the control circuit is wired correctly to the auxiliary contacts. Once installed, use the adjustment dial on the front of the unit to set the current value according to the motor's nameplate rating.
What to consider before purchase
Verify that the motor's full-load current falls within the 4-6A range
Ensure compatibility with your existing contactor model
Check the environmental conditions of the installation site
Confirm that the control circuit voltage matches the relay specifications
For optimal performance, regularly inspect the relay for any signs of physical wear and verify that the current setting remains aligned with the motor's operational requirements during routine maintenance checks.
