BR-20 4P 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 protect sensitive equipment and ensure system reliability, surge protective devices (SPDs) play a crucial role. The BR-20 4P Type 2 20kA Surge Protective Device is specifically designed for TNS (Terra-Neutral-Separated) systems, offering robust protection against these harmful surges.
Key Features of the BR-20 4P Type 2 SPD
The BR-20 4P Type 2 SPD is engineered to provide high-performance surge protection for TNS electrical installations. Here are its standout features:
- 20kA Nominal Discharge Current (In) – Capable of handling high surge currents, ensuring reliable protection.
- 4-Pole Design – Protects all phases and the neutral conductor in a TNS system.
- Type 2 Classification – Designed for installation at distribution boards, offering secondary protection.
- Thermal Disconnector – Safely disconnects the SPD in case of overload, preventing damage to the system.
- Visual Status Indicator – Provides clear indication of the device’s operational status.
Why Choose the BR-20 for TNS Systems?
TNS systems, where the neutral and protective earth conductors are separated, require specialized surge protection to ensure safety and performance. The BR-20 4P Type 2 SPD is tailored for such configurations, offering:
- Enhanced Safety – Prevents overvoltages from damaging equipment and causing electrical hazards.
- Compliance with Standards – Meets IEC 61643-11 and other relevant standards for surge protection.
- Easy Installation – Designed for straightforward integration into existing TNS distribution panels.
Applications of the BR-20 SPD
The BR-20 4P Type 2 20kA SPD is ideal for a variety of applications, including:
- Commercial and industrial electrical distribution systems
- Data centers and telecommunications facilities
- Healthcare and educational institutions
- Residential buildings with sensitive electronic equipment
Conclusion
Protecting electrical systems from transient surges is essential to avoid downtime, equipment damage, and safety risks. The BR-20 4P Type 2 20kA Surge Protective Device provides a reliable and efficient solution for TNS systems, ensuring optimal performance and longevity of connected equipment. Investing in high-quality SPDs like the BR-20 is a proactive step toward safeguarding your electrical infrastructure.
