• Rated Voltage (Un): 230V AC
• Maximum Continuous Operating Voltage (Uc): 320V AC
• Nominal Discharge Current (In): 20kA (8/20μs)
• Maximum Discharge Current (Imax): 40kA (8/20μs)
• Voltage Protection Level (Up): ≤1.5kV
• Response Time: ≤25ns
• Protection Mode: L-N, N-PE
• Operating Temperature Range: -40°C to +80°C
• Enclosure Protection: IP20
• Mounting: DIN rail (35mm)

Applications

The BR-40 2P Type 2 SPD is suitable for a wide range of applications, including:

• Residential Buildings: Protects household appliances, lighting systems, and smart home devices from power surges.
• Commercial Facilities: Safeguards office equipment, servers, and communication systems.
• Industrial Plants: Ensures the reliability of machinery, control systems, and automation equipment.
• Data Centers: Prevents downtime and data loss by shielding critical IT infrastructure.
• Renewable Energy Systems: Protects solar inverters and wind turbine controls from transient voltages.

Installation Guide

Follow these steps for proper installation of the BR-40 2P SPD:

1. Power Off: Ensure the main power supply is disconnected before installation.
2. Mounting: Attach the SPD to a 35mm DIN rail in the distribution board.
3. Wiring: Connect the live (L) and neutral (N) conductors to the corresponding terminals on the SPD.
4. Grounding: Establish a low-impedance connection to the grounding system (PE).
5. Verification: After installation, restore power
