3 Phase Type 2 SPD BR30FU 30kA Surge Protection Device
In today’s electrical systems, protecting equipment from voltage surges is critical. The 3 Phase Type 2 SPD BR30FU 30kA is a high-performance surge protection device designed to safeguard three-phase electrical installations against transient overvoltages.
Key Features of the BR30FU 30kA SPD
The BR30FU offers several advanced features that make it an ideal choice for industrial and commercial applications:
- 30kA discharge capacity per phase (Imax)
- Compact DIN rail mounting design
- Visual status indication for quick monitoring
- Thermal disconnector for safe operation
- Remote signaling contact for system integration
Applications
This surge protection device is particularly suitable for:
- Main distribution boards
- Industrial control panels
- Commercial buildings
- Data centers
- Renewable energy systems
Technical Specifications
| Parameter | Value |
|---|---|
| Nominal Voltage (Un) | 400V AC |
| Maximum Continuous Operating Voltage (Uc) | 440V AC |
| Nominal Discharge Current (In) | 15kA (8/20μs) |
| Maximum Discharge Current (Imax) | 30kA (8/20μs) |
| Protection Level (Up) | ≤ 2.5kV |
Installation Considerations
When installing the BR30FU SPD:
- Mount on 35mm DIN rail in the distribution board
- Connect according to the wiring diagram provided
- Ensure proper earthing connection
- Install upstream overcurrent protection as required
- Follow all local electrical codes and regulations
Maintenance and Monitoring
The BR30FU features a visual indicator that shows the operational status of the device. Regular inspection is recommended to ensure proper functioning. The SPD should be replaced when the status indicator shows end-of-life condition or after a significant surge event.
For optimal protection, the BR30FU can be used in combination with Type 1 SPDs at the service entrance and Type 3 SPDs near sensitive equipment, creating a comprehensive surge protection strategy.
