BR-20 3+1 Type 2 20kA Surge Protective Device for TT and TNS Systems
Electrical systems are vulnerable 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) are essential. The BR-20 3+1 Type 2 20kA Surge Protective Device is a high-performance solution designed for both TT and TNS earthing systems.
Key Features of the BR-20 3+1 Type 2 SPD
The BR-20 3+1 Type 2 SPD offers several advanced features that make it an ideal choice for surge protection:
- 20kA Surge Current Capacity: Capable of handling high surge currents up to 20kA (8/20μs), ensuring robust protection for electrical installations.
- 3+1 Configuration: Designed with three live conductors (L1, L2, L3) and one neutral conductor (N) for comprehensive protection in three-phase systems.
- Compatibility with TT and TNS Systems: Suitable for both TT (earth electrode) and TNS (separate neutral and earth) earthing systems, providing flexibility in installation.
- Type 2 Classification: Meets the requirements for Type 2 SPDs, which are installed at distribution boards to protect against indirect lightning strikes and switching transients.
- Visual Status Indication: Equipped with an indicator to show the operational status of the device, simplifying maintenance and troubleshooting.
Applications of the BR-20 3+1 Type 2 SPD
The BR-20 3+1 Type 2 SPD is widely used in various applications, including:
- Commercial and industrial buildings
- Data centers and telecommunications facilities
- Residential complexes with three-phase power supply
- Renewable energy installations, such as solar power systems
Installation and Maintenance
Installing the BR-20 3+1 Type 2 SPD is straightforward, but it should always be performed by a qualified electrician. The device is typically mounted on a DIN rail within a distribution board. Regular inspection of the status indicator is recommended to ensure the SPD remains functional. If the indicator shows a fault, the device should be replaced promptly to maintain protection.
Why Choose the BR-20 3+1 Type 2 SPD?
The BR-20 3+1 Type 2 SPD stands out due to its high surge current capacity, compatibility with multiple earthing systems, and reliable performance. By investing in this surge protective device, you can safeguard your electrical infrastructure, reduce downtime, and extend the lifespan of connected equipment.
