320VAC – Compatible with standard 3-phase 230/400V AC networks, providing stable protection across all phases and neutral.
• Surge Suppression Capability:
- Max. Discharge Current (Imax): 40kA (8/20 µs) – Effectively diverts large surge currents generated by lightning or switching events.
- Nominal Discharge Current (In): 20kA (8/20 µs) – Built to handle frequent surge events reliably over time.
• Low Voltage Protection Level (Up):
< 1.5kV – Ideal for safeguarding sensitive electronics and ensuring compliance with equipment withstand levels.
• Hybrid Technology:
Advanced SPD design combines Varistor and Gas Discharge Tube (GDT) elements for superior surge handling with extended durability.
• Visual Status Indicator:
Equipped with a built-in monitoring window:
- Green indicates normal operation
- Red signals that replacement is required
• Multi-Line Connection:
Supports connection to L1, L2, L3, N, and PE, ensuring complete protection for all conductors in a 3-phase system.
• DIN Rail Mounting:
Compact and modular design for easy installation in electrical cabinets, panel boards, and industrial enclosures.
• Global Standard Compliance:
Certified to IEC 61643-11, ensuring internationally recognized surge protection quality and safety.
