Citel DS240S-230/G SPD, compact, type 2, 1-phase, 20kA

Product Overview

The DS240S-230/G is a compact Type 2 (or Type 3) AC surge protector designed to protect single-phase networks at the main switchboard level in 230V applications. This modular SPD features hybrid MOV+GSG (Metal Oxide Varistor + Gas-filled Spark Gap) technology with integrated thermal disconnectors, providing both common mode and differential mode protection with pluggable modules, a fixed base for easy maintenance, and built-in remote signaling capability for enhanced monitoring.

Key Features:

• Hybrid Protection Technology: Combines MOV and gas-filled spark gap (GSG) for enhanced surge suppression with no residual current
• Dual Mode Protection: Provides both common mode (L-PE, N-PE) and differential mode (L-N) protection
• Compact Modular Design: Pluggable module with fixed base configuration for rapid maintenance and replacement without system shutdown
• High Discharge Capacity: Nominal discharge current of 20kA with maximum discharge current of 40kA (8/20μs)
• Remote Signaling: Integrated changeover contact output for remote status monitoring and facility management integration
• Thermal Protection: Equipped with thermal disconnectors and visual fault indicators for standards compliance
• UL1449 Type 4CA: Certified for use in North American applications including hazardous locations (UL121201)
• 10-Year Warranty: Long-term reliability with comprehensive manufacturer warranty
• Zero Leakage Current: Gas spark gap technology ensures no residual current to ground
• Easy Installation: DIN rail compatible with screw terminal connections for flexible mounting
