# 3 Phase Type 2 SPD BR30FU 30kA Surge Protection Device

## Introduction to Surge Protection Devices

Surge Protection Devices (SPDs) play a crucial role in safeguarding electrical systems from voltage spikes and transient surges. The 3 Phase Type 2 SPD BR30FU 30kA is a robust solution designed to protect three-phase electrical installations against lightning-induced surges and switching transients.

## Key Features of BR30FU 30kA SPD

The BR30FU model offers several important features:

– 30kA maximum discharge current per phase
– Compact and modular design for easy installation
– Thermal disconnector for enhanced safety
– Visual status indication for quick monitoring
– Suitable for TN-S, TN-C-S, and TT earthing systems

## Technical Specifications

Parameter | Value

## Installation and Applications

The BR30FU is typically installed in distribution boards to protect downstream equipment. Its primary applications include:

– Industrial facilities
– Commercial buildings
– Data centers
– Healthcare institutions
– Any three-phase electrical installation requiring surge protection

## Why Choose Type 2 SPD?

Type 2 SPDs like the BR30FU 30kA offer the perfect balance between protection level and cost-effectiveness. They provide:

– Secondary protection when installed after a Type 1 SPD
– Standalone protection in areas with lower lightning risk
– Effective protection against switching transients
– Long service life with proper maintenance

## Maintenance Considerations

To ensure optimal performance:

– Regularly check the status indicator
– Replace the module if the indicator shows failure
– Perform annual inspections by qualified personnel
– Keep records of installation and maintenance dates

The 3 Phase Type 2 SPD BR30FU 30kA is an essential component for modern electrical installations, providing reliable protection against transient overvoltages that could otherwise damage sensitive equipment and disrupt operations.
