BR-20 4P Type 2 20kA Surge Protective Device for 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 4P Type 2 20kA Surge Protective Device is specifically designed for TNS (Terra-Neutral-Separated) systems, offering robust protection against 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 with the following features:

• 20kA Surge Current Capacity: Capable of handling high-energy surges, ensuring long-term protection for electrical installations.
• 4-Pole Design: Protects all phases and the neutral conductor, making it ideal for three-phase TNS systems.
• Type 2 Classification: Designed to protect against indirect lightning strikes and switching transients.
• Thermal Disconnect Technology: Automatically disconnects in case of overload, preventing damage to the SPD and connected equipment.
• Visual Status Indicators: Provides clear indication of operational status and end-of-life warnings.

Why Choose the BR-20 for TNS Systems?
