## Summary description

HiSmart NV821686 is a single-pole (1P) surge protection device Class B rated for operation at 385VAC with a nominal discharge capacity in the 30–60 kA range. Designed to protect electrical installations and connected equipment from high-energy transients and lightning-induced surges, it is suitable for use in residential, commercial, and light industrial distribution boards. The device installs in-line on the supply and reduces risk of damage to sensitive electronics and appliances.

## Long description

HiSmart NV821686 is a single-pole (1P) surge protection device Class B designed for installation in the incoming low-voltage distribution box to protect electrical installations and connected equipment from high-energy transients and lightning-induced surges. Rated for a maximum continuous operating voltage of 385 V AC, the device supports system types TT, IT, TN-S, TN-C and TN-C-S and complies with IEC 61643-1 and relevant GB and CE standards.
Advantages
The device provides a high maximum discharge current (Imax) of 60 kA and a nominal discharge current (In) of 30 kA, ensuring robust handling of lightning stroke currents up to 100 kA when installed correctly. With a fast response time below 25 ns and a voltage protection level (Up) of ≤2.2 kV, it limits overvoltage propagation to downstream equipment. Compact dimensions and DIN-rail (35 mm) mounting simplify installation in standard distribution boards.
Suitable for
Protection of residential distribution boards and main incoming lines
Commercial and light industrial low-voltage distribution panels
Systems configured as TT, IT, TN-S, TN-C and TN-C-S
Areas prone to lightning-induced transients
