Citel DS240S-110DC SPD, compact, type 2, DC/PV network, 110VDC

Product Overview

The DS240S-110DC is a compact Type 2 DC power surge protector designed to protect equipment connected to 110Vdc DC and photovoltaic power supplies from lightning surges and transient overvoltages. This 2-pole modular SPD features metal oxide varistor (MOV) technology with integrated thermal disconnection, providing reliable protection with very low protection levels for DC systems, solar installations, and battery-powered applications operating at 110Vdc nominal voltage.

Key Features:

• MOV Technology: Metal oxide varistor-based protection matched to network voltage for optimal surge suppression
• High Surge Capacity: Maximum discharge current of 40kA per module (8/20μs) with 80kA total system capacity
• Compact Modular Design: Pluggable module configuration for easy installation and replacement
• Thermal Protection: Integrated thermal disconnection devices to control end-of-life with visual fault indicator
• Remote Signaling: Built-in changeover contact for remote status indication and monitoring
• Very Low Protection Level: Optimized voltage protection rating (Up) for sensitive electronic equipment
• Dual Network Compatibility: Suitable for both DC power networks and photovoltaic (PV) systems
• Low Leakage Current: Residual current less than 0.2mA at maximum operating voltage
• 10-Year Warranty: Long-term reliability with comprehensive manufacturer warranty
• UL Compliant Design: Type 4CA rating for North American installations
