Product information

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).

Suitable for

  • Incoming line low-voltage distribution boards in homes and apartments
  • Commercial building distribution panels
  • Light industrial electrical distribution
  • Protection of sensitive equipment such as control panels and communication devices

How to use

Install the HiSmart NV821716 on a standard 35 mm DIN rail inside the incoming-line low-voltage distribution box according to local electrical codes. Connect the four poles to the corresponding phases and neutral/earth terminals following the wiring diagram provided by the installer or manufacturer. Ensure correct earthing and system compatibility (TT, IT, TN-S, TN-C, TN-C-S) before energizing the circuit. After installation, verify connections and test the distribution board and downstream protection devices per applicable procedures.

Usage recommendations

For reliable protection, pair the surge protection device with proper earthing and upstream circuit protection. Periodically inspect the unit and the distribution board; replace the SPD if it shows signs of damage or after major surge events. Observe the 24-month manufacturer warranty conditions and perform installation by a qualified electrician in accordance with local regulations.
