Citel DS131R-230 SPD, type 1+2, AC, 1-pole Part number 571501

Product Overview

The DS131R-230 is an extreme duty Type 1+2 AC surge protector designed to protect the entrance of electrical installations in 230/400V applications. This single-pole SPD features combined Type 1 and Type 2 protection with 12.5kA impulse current capability, providing comprehensive protection against both direct lightning strikes and indirect surges in common mode or differential mode configurations for multipolar installations.

Key Features:

• Combined Type 1+2 Protection: Provides both primary (Type 1) and secondary (Type 2) surge protection in a single device
• High Impulse Current Rating: 12.5kA impulse current capability (10/350μs) for direct lightning strike protection
• Modular Single-Pole Design: Individual pluggable module for each phase allowing flexible multipolar configuration
• High Discharge Capacity: 20kA nominal discharge current with 50kA maximum discharge (8/20μs)
• Dual Mode Capability: Can be used in common mode or common and differential mode protection
• DIN Rail Compatible: Standard DIN rail mounting for easy installation
• Remote Signaling Option: Optional DS131RS-230 version available with changeover contact for remote monitoring
• Extreme Duty Rated: Designed for service entrance protection in high-risk lightning areas
