# 3 Phase Type 2 SPD BR30FU 30kA Surge Protection Device
## Introduction to Surge Protection Devices
Surge Protection Devices (SPDs) are essential components in modern electrical systems. They safeguard sensitive equipment from voltage spikes caused by lightning strikes, power surges, or switching operations. The 3 Phase Type 2 SPD BR30FU 30kA represents a robust solution for commercial and industrial applications where three-phase power distribution is common.
## Key Features of BR30FU SPD
The BR30FU model offers several important features:
– 30kA maximum discharge current per phase
– Type 2 classification (suitable for installation at distribution boards)
– Three-phase protection in a compact unit
– Visual status indicators for quick monitoring
– Thermal disconnectors for enhanced safety
## Technical Specifications
This surge protector is designed to meet rigorous performance standards:
Rated voltage: 400V AC (3-phase)
Nominal discharge current (In): 20kA
Maximum discharge current (Imax): 30kA
Voltage protection level (Up): ≤1.8kV
Response time: <25ns
Operating temperature range: -40°C to +80°C
## Installation Considerations
Proper installation is crucial for optimal performance:
Mounting Requirements
The BR30FU should be installed close to the main distribution board, preferably within 10 meters of the equipment being protected. It requires DIN rail mounting (35mm) and should be positioned for easy visual inspection of status indicators.
Wiring Guidelines
Use appropriate cable sizes according to local regulations. The SPD must be connected in parallel to the electrical system with proper overcurrent protection. All connections should be tight and secure to ensure low impedance paths for surge currents.
## Applications
This three-phase SPD is ideal for:
– Industrial facilities
– Commercial buildings
– Data centers
– Healthcare institutions
– Manufacturing plants
– Any location with sensitive three-phase equipment
## Maintenance and Monitoring
Regular inspection of the BR30FU is recommended to ensure continued protection. The device features visual indicators that show operational status – green for normal operation and red when replacement is needed. While the unit is maintenance-free, it should be replaced after a significant surge event or according to manufacturer recommendations.
