BR-40 3P Type 2 40kA Surge Protective Device for TN-C Systems
In today’s electrical infrastructure, protecting sensitive equipment from power surges is crucial. The BR-40 3P Type 2 40kA Surge Protective Device (SPD) is specifically designed for TN-C systems, offering robust protection against transient overvoltages. With a high discharge capacity of 40kA, this device ensures reliable safeguarding for industrial, commercial, and residential applications.
Key Features of the BR-40 3P Type 2 SPD
The BR-40 3P Type 2 SPD stands out due to its advanced engineering and performance capabilities:
- High Surge Capacity: 40kA per phase, ensuring maximum protection against lightning strikes and switching surges.
- TN-C Compatibility: Specifically optimized for TN-C earthing systems, providing safe and efficient surge diversion.
- Type 2 Classification: Designed to handle indirect surges and residual lightning currents, making it ideal for secondary protection.
- Compact and Durable: Robust construction with thermal disconnectors for fail-safe operation.
- Visual Status Indicators: Easy-to-read LED indicators for real-time monitoring of device health.
Why Choose the BR-40 for TN-C Systems?
TN-C systems combine the neutral and protective earth conductors into a single conductor (PEN). While cost-effective, this setup can introduce risks during surge events. The BR-40 3P SPD addresses these challenges by:
- Providing low let-through voltage to minimize equipment damage.
- Ensuring rapid response to transient surges (nanosecond-level reaction time).
- Maintaining system stability without interfering with normal operations.
Installation and Applications
The BR-40 is designed for easy installation in distribution boards or main panels. It is widely used in:
- Industrial facilities with heavy machinery.
- Commercial buildings with critical IT infrastructure.
- Residential complexes requiring surge protection for appliances.
For optimal performance, the SPD should be installed by a qualified electrician in accordance with local regulations and manufacturer guidelines.
Conclusion
The BR-40 3P Type 2 40kA Surge Protective Device is a reliable solution for TN-C systems, combining high surge suppression with user-friendly features. Whether safeguarding industrial equipment or household electronics, this SPD delivers peace of mind in an increasingly electrified world.
