# 3-Phase Type 2 SPD BR30FU 30kA Surge Protection Device
## Introduction to Surge Protection Devices (SPDs)
In today’s increasingly electrified world, protecting electrical systems from voltage surges has become more critical than ever. The 3-Phase Type 2 SPD BR30FU 30kA is a robust solution designed to safeguard three-phase electrical installations against transient overvoltages.
## Key Features of the BR30FU SPD
The BR30FU surge protection device offers several important features:
Keyword: 3 phase type 2 spd br30fu 30ka
– 30kA maximum discharge current per phase
– Designed for three-phase systems (L1, L2, L3, N, PE)
– Type 2 classification according to IEC 61643-11
– Compact and modular design for easy installation
– Visual status indication for quick monitoring
## Technical Specifications
Parameter | Value

## Installation and Application
The BR30FU is typically installed in distribution boards to protect against surges originating from:
– Lightning strikes (indirect effects)
– Switching operations in the power grid
– Electrical load changes within the facility
Installation should be performed by qualified electricians following local electrical codes and the manufacturer’s instructions. The device should be connected between phase conductors and the protective earth (PE) conductor.
## Maintenance and Monitoring
Regular inspection of the BR30FU is recommended to ensure proper operation:
– Check the visual status indicator (green = OK, red = replace)
– Verify tightness of connections during routine maintenance
– Replace the module if it has operated or shows signs of damage
## Why Choose the BR30FU?
This surge protection device offers:
– High surge current handling capacity
– Reliable protection for sensitive equipment
– Compliance with international standards
– Easy integration into existing electrical systems
– Cost-effective solution for surge protection
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.
