Genius RT1B Thermal Overload Relay, 0.16 - 0.26A, Class 10

The Genius RT1B thermal overload relay is a precision-engineered component designed to provide reliable protection for electric motors against thermal damage caused by overloads. With an adjustable current setting range of 0.16 to 0.26A and a trip class 10 rating, this device ensures that industrial electrical systems remain operational and safe. By monitoring current flow, the relay automatically disconnects the circuit during prolonged overcurrent conditions, effectively preventing motor overheating and potential mechanical failure.

Advantages

This thermal overload relay offers a robust solution for motor management, featuring high sensitivity and consistent performance in demanding industrial environments. Its adjustable current range allows for precise calibration to match the specific requirements of the connected motor, ensuring optimal protection without nuisance tripping. The compact design facilitates easy integration into existing control panels, while the reliable trip mechanism provides peace of mind by safeguarding expensive equipment from electrical faults.

Suitable for

• Industrial motor control centers
• HVAC system motor protection
• Conveyor belt drive systems
• Pump and fan motor applications
• Automation and manufacturing machinery

This relay is not suitable for applications where the motor current exceeds the 0.26A threshold or for environments requiring a trip class other than 10. It is also not intended for use as a primary short-circuit protection device, as it is specifically designed to handle thermal overloads rather than instantaneous high-current faults.

Key specifications

• Adjustable current range: 0.16 - 0.26A
• Trip class: 10
• Function: Thermal overload protection
• Application: Motor circuit protection

To use the Genius RT1B, mount the relay directly onto the corresponding contactor or via a DIN rail adapter if required. Once installed, use the adjustment dial on the front of the unit to set the current limit according to the motor's full-load amperage rating. Ensure all electrical connections are tightened securely to prevent resistance and heat buildup. The device will automatically monitor the current and trip the circuit if the motor experiences a sustained overload.

What to consider before purchase

• Verify the full-load current rating of your motor matches the 0.16 - 0.26A range
• Ensure compatibility with your existing contactor model
• Confirm the required trip class for your specific application
• Check the environmental conditions of the installation site

For optimal performance and safety, always ensure the relay is calibrated to the specific motor nameplate data and perform periodic inspections of the electrical connections to maintain system integrity.
