3-Phase Type 2 SPD BR30FU with 30kA Protection: A Comprehensive Guide
Introduction to Surge Protection Devices (SPDs)
Surge Protection Devices (SPDs) are essential components in modern electrical systems, safeguarding equipment from transient overvoltages caused by lightning strikes, switching operations, or other electrical disturbances. Among the various types available, the 3-Phase Type 2 SPD BR30FU with 30kA protection stands out as a robust solution for industrial and commercial applications.
Understanding the 3-Phase Type 2 SPD BR30FU
The BR30FU is a Type 2 SPD designed for three-phase electrical systems. It offers a high level of protection with a nominal discharge current (In) of 30kA, making it suitable for installations where significant surge currents are expected. This device is typically installed at the distribution board level, providing secondary protection after the main Type 1 SPD (if present).
Key Features of the BR30FU SPD
This surge protector boasts several important characteristics:
- 30kA nominal discharge current (In) – Provides robust protection against large surge currents
- Three-phase protection – Covers all phases (L1, L2, L3) and neutral
- Type 2 classification – Designed for installation at distribution boards
- Compact design – Space-efficient for panel mounting
- Visual status indication – Clear fault indication for easy maintenance

Proper installation is crucial for optimal performance of the BR30FU SPD:
Mounting Requirements
The device should be mounted on a DIN rail within the distribution panel, typically near the main incoming supply. Ensure there’s adequate space around the unit for ventilation and future maintenance.
Wiring Guidelines
Follow these wiring best practices:
- Use appropriately sized conductors (typically 6-10mm²)
- Keep connection leads as short as possible (ideally < 0.5m)
- Ensure proper earthing with low impedance connection
- Follow manufacturer’s torque specifications for terminal connections
