Product Details
Protect your electrical systems with the Type 2 20kA 275V 1P+N Surge Protective Device (SPD) with Aux contact, model NU6-II-G/F, from CHINT. Designed for modern residential, commercial, and light industrial installations, this surge protector guards against damaging voltage spikes caused by lightning strikes and transient overvoltage events. It is engineered to deliver dependable performance while helping extend the life of connected equipment.
This SPD provides a 20kA nominal discharge capacity, making it suitable for use in distribution boards and electrical panels operating at 275V AC. Its single-phase plus neutral (1P+N) configuration is compact and ideal for installations where space is limited. The unit mounts on a standard 35mm DIN rail and integrates easily with existing electrical systems.
A key feature of the NU6-II-G/F is the auxiliary contact. This allows remote signalling of the device status, so you can monitor whether the SPD remains operational or requires attention without opening the panel. This improves safety and makes maintenance easier, especially in automated or hard-to-reach installations.
The device is housed in a durable, flame-resistant enclosure and includes a clear visual fault indicator. This lets you quickly see when the surge module needs replacing. Its modular design supports straightforward maintenance without disconnecting the main circuit, helping reduce downtime and labour costs. The SPD is suitable for TN and TT earthing systems, making it a reliable choice for protecting consumer units, sensitive electronics, and essential appliances.
Whether you are installing a new electrical system or upgrading existing surge protection, the NU6-II-G/F SPD delivers dependable performance backed by CHINT quality and CE compliance.
