FUJI TR-0N/3 Thermal Overload Relay (0.95-1.45A)

Key Features:

1. Thermal Overload Protection:

   • The TR-0N/3 is designed to protect motors from overheating due to prolonged overcurrent. The thermal element inside the relay monitors the motor current and triggers the trip mechanism when the current exceeds the preset threshold, preventing potential damage to the motor.

2. Current Range:

   • The relay offers a current adjustment range of 0.95 to 1.45 A, making it suitable for motors that draw this current. It allows users to precisely set the trip point for optimal motor protection.

3. Adjustable Trip Setting:

   • The adjustable current setting allows users to customize the relay based on the specific motor's requirements, ensuring the protection is matched to the motor's rated current. This is important to ensure that the motor does not trip under normal operation.

4. Manual Reset Function:

   • After the relay trips due to an overload condition, it requires a manual reset to restart the motor. This ensures that operators can first address the underlying issue (such as excessive load or poor ventilation) before restarting the motor.

5. Visual Trip Indicator:

   • The relay features a visual trip indicator that makes it easy for operators to see when the relay has been activated due to an overload condition, facilitating quick identification and corrective action.

6. Compact and Efficient Design:

   • The TR-0N/3 is designed with a compact form factor, allowing for easy integration into electrical control panels. Its small size saves space while providing high functionality.

7. Phase Failure Protection:

   • In addition to protecting against thermal overloads, the TR-0N/3 also provides protection against phase failure or unbalanced phase conditions, which can cause damage to motors if they continue to run in these states.

8. Wide Temperature Range:

   • The relay operates effectively within a temperature range of -5°C to +40°C, ensuring reliable performance in various environmental conditions.

9. DIN Rail Mounting:

   • The TR-0N/3 is designed for DIN rail mounting, which simplifies installation in electrical control panels. It is compatible with standard DIN rail systems, ensuring quick and secure mounting.

Applications:

• Motor Protection: The TR-0N/3 is ideal for protecting AC motors in a wide range of applications where motors draw 0.95 to 1.45 A, such as in pumps, fans, conveyors, and industrial machinery.

• HVAC Systems: Commonly used in protecting motors in heating, ventilation, and air conditioning systems, where maintaining motor health is critical to the system’s overall performance.

• Small to Medium-Sized Motors: The TR-0N/3 is suited for small to medium-sized motors, providing cost-effective and reliable protection against thermal overload.

• Automation Equipment: Suitable for use in automated manufacturing and control systems, ensuring motor protection in continuous or frequent operations.
