Citel DS134VGS-230/G SPD, type 1+2+3, AC, 3P+N

Product Overview

The DS134VGS-230/G is an extreme-duty Type 1+2+3 combined surge protection device for electrical installation entrance protection in high lightning risk areas. Utilizing CITEL's patented VG technology combining metal oxide varistors with gas-filled spark gaps, this four-pole unit delivers 12.5 kA impulse current per pole with 50 kA total capacity while eliminating leakage and follow-on currents. The pluggable design with remote signaling provides optimal protection for 230/400V three-phase plus neutral TT-TNS networks.

Key Features:

• Patented VG Technology: Gas-filled spark gap combined with metal oxide varistor eliminates operating and leakage currents, prevents follow-on current generation, and achieves Type 1+2+3 protection in a single compact device.
• High Impulse Capacity: 12.5 kA impulse current per pole (10/350 µs) with 50 kA total and 20 kA nominal discharge current for direct lightning strike protection.
• Zero Leakage Operation: Galvanic isolation during normal operation eliminates varistor aging and ensures maximum lifespan without performance degradation.
• No Follow-On Current: Prevents mains follow-on current generation, ensuring continuous operation without upstream breaker tripping and maintaining power quality.
• Enhanced TOV Withstand: Handles temporary overvoltages up to 440 VAC and 1200V/300A/200ms transients for reliable operation in unstable networks.
• Pluggable Modules: Field-replaceable cartridges enable rapid replacement without disconnecting wiring, minimizing maintenance downtime.
• Individual Pole Indicators: Independent mechanical status indicator per pole provides real-time visual confirmation for immediate fault identification.
• Remote Signaling: Changeover contact output enables integration with building management systems and SCADA platforms for centralized monitoring.
