Product Description
Product Overview
The BR-25GR Type 1 Surge Protection Device is a coordinated spark-gap-based lightning current and surge arrester designed to discharge high current surges without installation destruction. This three-phase unit withstands impulse currents with 10/350 µs waveform, simulating direct lightning impacts.

Key Features & Benefits
- 25kA impulse current per pole (10/350 µs wave) meets all overvoltage surge protection requirements
- Ideal as first-step protection in incoming power supply panels and high atmospheric exposure areas
- Electronic ignition device creates early electric arc, reducing protection level to optimal 2.3kV
- Compact construction design for space-efficient installation
- Dedicated arc chamber extinguishes electrical arc following discharge
- Can open short circuits up to 50kA without backup protection
Application Areas
Type 1 Lightning Current Arresters are designed for installation at the origin of electrical systems in main switchboards, particularly in high-risk areas with probability of direct lightning strikes:
- Areas where direct lightning strikes to overhead lines between the last pole and installation entrance must be considered
- Structures equipped with lightning rods
