Overview of NU6-II 4P:

Power surges can silently damage expensive electrical systems, appliances, and sensitive equipment. The SPD NU6-II 4P surge protection device is designed to keep your residential, commercial, or industrial installations safe from transient overvoltages caused by lightning strikes, switching operations, or unstable grids.

With a four-pole (4P) design, this SPD is ideal for three-phase systems with neutral, offering comprehensive protection across all lines. If you want reliable surge safety for your distribution board, the NU6-II 4P is a solid choice.

What is SPD NU6-II 4P?

An SPD (Surge Protection Device) safeguards electrical networks by diverting dangerous surge currents safely to the ground. The NU6-II 4P is a Type II SPD, commonly used as the second line of defense in low-voltage distribution systems after the main lightning protection system.

• 4P (Four Pole): Protects three-phase plus neutral.
• Type II SPD: Designed for residential, commercial, and industrial distribution boards.
• High energy absorption capacity: Ensures durability and stable performance.

Key Features of NU6-II 4P:

• Reliable surge protection against transient overvoltage.
• Four-pole design for 3-phase + neutral systems.
• Modular, compact housing for easy installation.
• Visual fault indicator for quick status checks.
• High discharge current capacity for strong protection.
• Complies with IEC/EN 61643 standards.
