FUJI TR-0N/3 Thermal Overload Relay (1.7-2.6A)

Key Features:

1. Thermal Overload Protection:

   • The TR-0N/3 is designed to protect motors from overheating by detecting when the motor draws excessive current for too long, which can cause the motor windings to overheat and fail. The relay trips when the motor draws more current than its rated capacity for an extended period, ensuring that the motor does not suffer permanent damage.

2. Current Range:

   • The relay is specifically adjustable within the current range of 1.7 A to 2.6 A, making it suitable for protecting motors that operate within this current range. This adjustment allows users to fine-tune the relay for different types of motors or conditions.

3. Adjustable Trip Settings:

   • The TR-0N/3 allows for adjustable settings within the 1.7-2.6 A range, providing flexibility to match the exact current rating of the motor being protected. This ensures optimal protection based on the motor's load and application.

4. Manual Reset After Trip:

   • After the relay trips due to an overload, it requires a manual reset. This feature helps ensure that the operator acknowledges the overload condition and addresses the issue before restarting the motor, preventing further damage.

5. Visual Trip Indicator:

   • The visual trip indicator makes it easy to identify when the relay has tripped, signaling an overload condition. This allows for quick troubleshooting and corrective action, reducing downtime and improving system efficiency.

6. Compact and Space-Saving Design:

   • The TR-0N/3 is designed with a compact footprint, making it easy to integrate into electrical control panels, saving valuable space without compromising on performance.

7. Phase Failure Protection:

   • The relay provides phase failure protection, which helps safeguard motors against phase loss or unbalanced phases. These conditions can cause motor damage if left unchecked, and the TR-0N/3 prevents these issues by tripping the circuit when such conditions are detected.

8. Wide Operating Temperature Range:

   • This relay operates within a wide temperature range of -5°C to +40°C, ensuring reliable performance even in challenging environments where temperature fluctuations are common.

9. DIN Rail Mounting:

   • The TR-0N/3 can be easily mounted on a DIN rail, allowing for quick and secure installation in control panels. This feature makes the relay easy to incorporate into new or existing electrical systems.

Applications:

• Motor Protection: The TR-0N/3 is primarily used for protecting AC motors in various industrial and commercial applications, including pumps, fans, conveyors, small machinery, and HVAC systems.

• Industrial Equipment: Suitable for applications where motors operate within the 1.7-2.6 A range, providing cost-effective protection from thermal overloads and ensuring motor longevity.

• HVAC and Cooling Systems: Ideal for HVAC motors and cooling systems, ensuring the motors remain safe from overloads that can lead to expensive downtime and repairs.

• Automated Control Systems: Commonly used in automated manufacturing, production lines, and robotics where motors run continuously and require protection from thermal issues.
