Selection Guide

Choosing the right RT18 fuse for your application involves considering several key factors:

1. Voltage Rating

Select a fuse with a voltage rating equal to or greater than your system’s nominal voltage. The RT18 series offers options for AC400V, AC500V, and 690V systems.

2. Current Rating

Determine the maximum normal operating current of your circuit and select a fuse with an appropriate rating. Remember that fuses should be sized according to circuit conductor capacity and load requirements.

3. Breaking Capacity

Ensure the fuse’s breaking capacity (100kA for RT18 series) exceeds the maximum prospective short-circuit current at the point of installation.

4. Protection Class

Choose the appropriate protection class based on your application:

• gL/gG: For general conductor and cable protection
• aM: For motor circuit protection
• aR: For semiconductor protection

5. Physical Size

Select the appropriate physical dimensions based on your installation constraints and fuse holder requirements.

設置ガイドライン

For optimal performance and safety, follow these installation guidelines when using RT18 fuses:

1. Always ensure the power is disconnected before installing or replacing fuses
2. Verify that the fuse rating and size match your application requirements
3. Install fuses in appropriate holders designed for the specific size and rating
4. Ensure proper connection and tightening of all electrical terminals
5. Verify that the fuse orientation is correct (if applicable)
6. Check for any signs of damage before installation
7. Follow local electrical codes and standards during installation

Maintenance Recommendations

To ensure continued protection and reliability, consider these maintenance practices:

1. Regularly inspect fuses for signs of overheating, discoloration, or damage
2. Check fuse holders for secure connections and signs of wear
3. Replace blown fuses with identical ratings and types
4. Never attempt to repair or modify a fuse
5. Document fuse replacements to identify recurring issues
6. Conduct periodic thermal scanning to identify potential issues before failure
