## Long description

HiSmart NV821716 is a 4-pole surge protection device designed for low-voltage distribution systems with a maximum continuous operating voltage of 385 VAC. It provides protection against transient overvoltages and lightning-induced surges for residential, commercial and light industrial installations. The device is suitable for installation in incoming line distribution boxes and complies with IEC 61643-1, GB18802.1 and related standards.
Advantages
The HiSmart NV821716 offers four contacts for full 4-pole protection and is specified to handle high discharge currents with a nominal discharge current of 30 kA and a maximum discharge current up to 60 kA, enabling it to clear strong transient events. With a fast response time below 25 ns and a voltage protection level ≤ 2.2 kV, it reduces the risk of damage to connected equipment. The unit mounts on a 35 mm DIN rail and supports common earthing systems (TT, IT, TN-S, TN-C, TN-C-S).
