    This record is the 385 V AC / 20–40 kA version shown on manufacturer hardware, not the 420 V version in another regional title. Uc is the maximum continuous voltage across the SPD terminals; it is not the AC supply’s line-to-line voltage. Select the connection for the installation’s earthing system.

    What this product does in the system.

    Four-module AC surge protector with L1, L2, L3 and N connections. Uc 385 V AC, In 20 kA, Imax 40 kA and Up ≤ 1.8 kV. Connected in parallel with separate backup protection; it is neither a circuit breaker nor a residual-current device.

    Relevant applications

    • Commercial AC distribution

    Why ReneWave may shortlist it

    • Four-module AC surge protector with L1, L2, L3 and N connections. Uc 385 V AC, In 20 kA, Imax 40 kA and Up ≤ 1.8 kV. Connected in parallel with separate backup protection; it is neither a circuit breaker nor a residual-current device.

    What changes in practice

    • The four-module assembly connects L1, L2, L3 and N to the surge-protection branch with a separate PE connection. It does not switch these conductors or interrupt the load; the earthing-system connection must match the supplied drawing.
    • In is the nominal surge-discharge current and Imax the maximum surge-discharge current, both for an 8/20 µs pulse. They are not a 40 kA breaker rating. Coordinate backup protection, earth bonding and equipment impulse withstand; a rated backup fuse size is not established here.
    • Surge diversion only. No overload, short-circuit or residual-current protection; no protection guarantee against a direct lightning strike. Keep the circuit’s isolation and overcurrent devices separate.

    Four practical selection points.

    Match the circuit, surge ratings, earth connection and backup protection.

    1. 01

      Circuit and conductor arrangement

      The four-module assembly connects L1, L2, L3 and N to the surge-protection branch with a separate PE connection. It does not switch these conductors or interrupt the load; the earthing-system connection must match the supplied drawing.

    2. 02

      Voltage and surge ratings

      This record is the 385 V AC / 20–40 kA version shown on manufacturer hardware, not the 420 V version in another regional title. Uc is the maximum continuous voltage across the SPD terminals; it is not the AC supply’s line-to-line voltage. Select the connection for the installation’s earthing system.

    3. 03

      Separate backup protection

      In is the nominal surge-discharge current and Imax the maximum surge-discharge current, both for an 8/20 µs pulse. They are not a 40 kA breaker rating. Coordinate backup protection, earth bonding and equipment impulse withstand; a rated backup fuse size is not established here.

    4. 04

      Mounting and earth connection

      35 mm DIN rail mounting inside a suitable enclosure. Keep the parallel conductors and PE connection short. Follow the supplied revision’s terminal drawing; isolate before replacing a module. A red status window calls for inspection and replacement, not automatic resetting.
