BR-20 2P Type 2 20kA Surge Protective Device for TNS Systems
Electrical systems are vulnerable to power surges caused by lightning strikes, utility switching, or other transient voltage events. To protect sensitive equipment and ensure uninterrupted operation, surge protective devices (SPDs) are essential. The BR-20 2P Type 2 20kA Surge Protective Device is specifically designed for TNS (Terra Neutral Separate) systems, offering robust protection against transient overvoltages.
Key Features of the BR-20 2P Type 2 SPD
The BR-20 2P Type 2 SPD provides several critical features that make it an ideal choice for TNS electrical installations:
- 20kA Surge Current Capacity – Handles high-energy surges effectively
- Type 2 Classification – Protects against indirect lightning strikes and switching transients
- 2-Pole Design – Safeguards both line-to-neutral and line-to-ground connections
- Thermal Disconnect Technology – Prevents overheating and ensures safe operation
- Visual Status Indicator – Allows for easy monitoring of device health
Why Choose the BR-20 for TNS Systems?
TNS systems, where the neutral and protective earth conductors are separate, require specialized surge protection. The BR-20 2P Type 2 SPD is engineered to:
- Provide balanced protection across all phases and neutral
- Minimize voltage differentials between conductors
- Ensure compliance with IEC 61643-11 and other relevant standards
Installation and Applications
The BR-20 is designed for easy installation in distribution boards or load centers. It is commonly used in:
- Commercial buildings
- Industrial facilities
- Data centers
- Healthcare facilities
For optimal protection, the device should be installed at the main distribution panel and coordinated with other SPDs in a cascaded protection scheme.
Conclusion
The BR-20 2P Type 2 20kA Surge Protective Device offers reliable, high-performance protection for TNS electrical systems. Its robust design, high surge capacity, and specialized features make it an excellent choice for safeguarding critical equipment against damaging power surges.
