Citel DS250VG-300 SPD, unipolar, type 1+2+3, 230/400V

Product Overview

The DS250VG-300 is an extreme duty Type 1+2+3 single-pole AC surge protector designed to protect electrical installations at the service entrance in high lightning density areas. This heavy-duty SPD features patented VG hybrid technology combining metal oxide varistors with gas-filled spark gaps to handle very high surge currents up to 25kA on 10/350μs impulse, making it particularly suitable for buildings equipped with lightning rods and applications requiring maximum protection against direct and indirect lightning effects.

Key Features:

• Extreme Duty Protection: Type 1+2+3 classification with 25kA lightning impulse current capability (10/350μs) for direct strike protection
• VG Hybrid Technology: Patented combination of high-energy metal oxide varistors and gas-filled spark gaps for superior surge handling
• Zero Leakage Current: Gas tube technology ensures no leakage current to ground at maximum continuous operating voltage
• Low Protection Levels: Industry-leading low residual clamp voltage of 1200V at nominal discharge current
• High Discharge Capacity: Maximum discharge current of 70kA (8/20μs) with 30kA/20kA nominal discharge current
• Thermal Protection: Integral thermal disconnector compliant with UL 60691 with visual fault indicator
• Remote Signaling: Built-in contact for remote status indication (250Vac max, 2A)
• Dual Terminal Design: Double connection terminals for active conductor allowing optimized network connection and in-line wiring up to 250A
• Multi-Configuration Capability: Can be used in common mode or common and differential mode for single-phase, 3-phase, and 3-phase+Neutral networks
