BR-40 3P Type 2 40kA Surge Protective Device for TN-C Systems
Electrical systems are constantly exposed to transient overvoltages caused by lightning strikes, switching operations, or other disturbances. To safeguard sensitive equipment and ensure uninterrupted power supply, surge protective devices (SPDs) play a critical role. The BR-40 3P Type 2 40kA Surge Protective Device is specifically designed for TN-C systems, offering robust protection against high-energy surges.
Key Features of the BR-40 3P Type 2 SPD
The BR-40 3P Type 2 SPD is engineered to provide superior surge protection with the following features:
- High Discharge Capacity: With a nominal discharge current (In) of 20kA and a maximum discharge current (Imax) of 40kA, this SPD can handle significant surge currents.
- Type 2 Classification: Designed for installation at the distribution board level, it protects against indirect lightning strikes and switching transients.
- TN-C Compatibility: Specifically tailored for TN-C earthing systems, ensuring optimal performance and safety.
- Visual Status Indication: Equipped with an LED indicator to provide real-time status of the device’s operational condition.
- Thermal Disconnector: Includes a built-in thermal protection mechanism to prevent overheating and ensure safe operation.
Applications of the BR-40 3P Type 2 SPD
This surge protective device is ideal for a variety of applications, including:
- Commercial and industrial electrical distribution panels
- Residential buildings with TN-C earthing systems
- Data centers and telecommunication facilities
- Medical facilities requiring reliable power protection
Why Choose the BR-40 3P Type 2 SPD?
The BR-40 3P Type 2 SPD stands out due to its combination of high performance, reliability, and ease of installation. Its robust design ensures long-term protection for electrical systems, minimizing downtime and equipment damage.
