FUJI TR-5-1N/3 Thermal Overload Relay (0.8-1.2A)

Key Features:

1. Thermal Overload Protection:

   • The TR-5-1N/3 is designed to protect motors from thermal overload, which occurs when the motor is drawing more current than it is rated for over an extended period, causing overheating. The relay provides protection by breaking the circuit once the temperature exceeds safe levels, preventing motor failure.

2. Current Range:

   • The TR-5-1N/3 relay is specifically adjustable within the current range of 0.8 to 1.2 A, which makes it suitable for motors operating within this current range. The adjustable trip point allows it to be fine-tuned to match the motor's requirements.

3. Adjustable Trip Point:

   • The TR-5-1N/3 offers an adjustable trip setting, allowing for customization based on the specific motor and application needs. This feature enables users to set the appropriate threshold for overload protection.

4. Manual Reset:

   • After a trip event, the TR-5-1N/3 relay requires a manual reset to restore operation. This ensures that the overload condition is addressed before the motor can restart.

5. Compact Design:

   • The compact design of the TR-5-1N/3 relay allows for easy integration into electrical control systems, reducing the overall space requirement. It is designed to fit into standard relay panels, making it an efficient choice for industrial motor protection.

6. Wide Operating Temperature Range:

   • This thermal overload relay is capable of operating in a wide temperature range, typically from -5°C to +40°C, making it suitable for a variety of environmental conditions.

7. Protection Against Phase Failure:

   • The TR-5-1N/3 also provides protection against phase failure, which occurs when one phase of the motor power supply is lost. This feature ensures that the motor is not damaged when running under unbalanced conditions.

8. Indication of Trip Condition:

   • The relay provides visual indicators to signal when an overload condition has been triggered, allowing operators to quickly identify when a fault has occurred and take corrective action.

9. Versatile Mounting Options:

   • The TR series relays, including the TR-5-1N/3, are designed for easy mounting on a DIN rail, ensuring quick installation and secure placement within control panels or motor control centers.
