# 25kA Surge Arrester 25GR 4P Type 1 for Enhanced Electrical Protection
## Introduction to Surge Protection
In today’s increasingly electrified world, protecting electrical systems from power surges has become more critical than ever. The 25kA Surge Arrester 25GR 4P Type 1 represents a robust solution for safeguarding equipment against transient overvoltages that can cause significant damage.
## Understanding the 25kA Surge Arrester 25GR 4P Type 1
Key Specifications
The 25kA designation indicates this arrester can handle surge currents up to 25,000 amperes, making it suitable for demanding applications. The 25GR model features a compact design while maintaining excellent protection capabilities. As a 4P (four-pole) device, it provides comprehensive protection for three-phase systems with neutral.
Type 1 Classification
Being classified as Type 1 means this surge arrester is designed for installation at the service entrance, where it can protect against direct lightning strikes and other high-energy transients. This makes it particularly valuable for industrial facilities, commercial buildings, and critical infrastructure.
## Technical Features and Benefits
Superior Protection
The 25GR 4P Type 1 arrester offers:
- High discharge capacity (25kA 8/20μs per pole)
- Fast response time (<25ns)
- Low residual voltage for optimal equipment protection
- Thermal disconnector for safe failure mode
Durability and Reliability
Constructed with high-quality materials, this surge arrester is built to withstand harsh environmental conditions while maintaining consistent performance over time. Its robust design ensures long-term reliability with minimal maintenance requirements.
## Installation and Application
Proper Installation Guidelines
For optimal performance:
- Install at the main distribution panel or service entrance
- Ensure proper grounding connections
- Follow all local electrical codes and regulations
- Consider pairing with Type 2 arresters for complete protection
