CHINT NU6-IIG 40/440 2P 400V AC Surge Protection Device (SPD) – Lightning & Overvoltage Protection

₨ 6,299

The CHINT NU6-IIG 40/440 2P SPD is a reliable surge protection device designed to protect electrical systems from lightning strikes and transient overvoltage. Ideal for residential, commercial, and industrial applications with DIN rail mounting.

The CHINT NU6-IIG 40/440 2P 400V AC Surge Protection Device (SPD) is a high-performance protection solution engineered to safeguard electrical installations from lightning-induced surges and transient overvoltages. It is an essential component for ensuring the safety and longevity of sensitive electrical and electronic equipment.

Designed for AC 230/400V systems operating at 50/60Hz, this SPD features a 2-pole (2P) configuration, making it suitable for single-phase systems. It effectively diverts surge energy to ground, minimizing damage caused by sudden voltage spikes and ensuring stable system performance.

With a maximum continuous operating voltage (Uc) of up to 440V and a high discharge capacity (Imax up to 40kA), the device offers strong protection against high-energy surges. It also features a low voltage protection level (Up), ensuring sensitive equipment remains protected during transient events.

The NU6-IIG series is built according to IEC/EN 61643-11 standards, ensuring international safety compliance and reliable performance. It supports various grounding systems (TN-S, TN-C, TT, IT), making it versatile for different installation environments.

Its modular design includes replaceable protection modules and a visual fault indicator, allowing easy maintenance and quick status checks. The compact DIN rail mounting design ensures simple installation in distribution boards, making it ideal for modern electrical panels.

This SPD is widely used in homes, offices, factories, and solar systems where protection against voltage surges is critical for maintaining uninterrupted operation and preventing costly equipment damage.
