BR-20 2P Type 2 20kA Surge Protective Device for TNS Systems

Electrical systems are constantly exposed to transient overvoltages caused by lightning strikes, switching operations, or other electrical disturbances. To safeguard sensitive equipment and ensure uninterrupted operation, surge protective devices (SPDs) play a crucial role. The BR-20 2P Type 2 20kA Surge Protective Device is specifically designed for TNS (Terra-Neutral-Separated) systems, offering reliable protection against these harmful surges.

Key Features of the BR-20 2P Type 2 SPD

The BR-20 2P Type 2 SPD boasts several features that make it an ideal choice for TNS systems:

• 20kA Nominal Discharge Current (In): Capable of handling high surge currents, ensuring robust protection.
• Type 2 Classification: Designed to protect against indirect lightning strikes and switching transients.
• 2-Pole Configuration: Suitable for single-phase TNS systems, providing protection between line and neutral.
• Compact Design: Easy to install in distribution boards or enclosures.
• Visual Status Indication: Allows for quick inspection of the device’s operational status.

Why Choose the BR-20 for TNS Systems?

TNS systems, where the neutral and protective earth are separate, require specialized surge protection. The BR-20 2P Type 2 SPD is engineered to meet these requirements by:

• Providing coordinated protection between live conductors and earth.
• Ensuring compliance with international standards such as IEC 61643-11.
• Minimizing downtime by preventing damage to connected equipment.

Installation and Maintenance

Installing the BR-20 2P Type 2 SPD is straightforward, but it should always be performed by a qualified electrician. Key installation tips include:

• Mount the device close to the equipment it is protecting.
• Ensure proper grounding to maximize effectiveness.
• Regularly inspect the status indicator to confirm the SPD is functional.

For optimal performance, replace the SPD after a significant surge event or as recommended by the manufacturer.

Conclusion

The BR-20 2P Type 2 20kA Surge Protective Device is a reliable solution for protecting TNS systems against transient overvoltages. With its high discharge capacity, Type 2 classification, and user-friendly design, it ensures the safety and longevity of electrical installations. Investing in quality surge protection like the BR-20 can save costly equipment repairs and downtime in the long run.
