    AC 275 V/385V SPD Surge Protection Device 2 Pole Surge ...
    An AC 385V SPD (Surge Protective Device) is a Type 2 or Type 1+2 protective component used in 50/60Hz low-voltage systems to guard against lightning and transient overvoltages . Operating at a maximum continuous voltage (
    U c cap U sub c
    𝑈 𝑐
    ) of 385V, these devices commonly feature 1P, 2P, 3P, or 4P configurations with nominal discharge currents (
    I n cap I sub n
    𝐼 𝑛
    ) of 20kA and maximum discharge currents (
    I m a x cap I sub m a x end-sub
    𝐼 𝑚 𝑎 𝑥
    ) of 40kA–100kA.
    Key Technical Specifications & Features
    • Voltage Rating: 385V (AC) - suitable for higher-voltage AC networks than 275V models.
    • SPD Type: Primarily Type 2, with some Type 1+2 options for combined protection.
    • Safety Features: Visual indicators (Green=OK, Red=Replace) and optional remote signaling contacts.
    • Installation: 35mm DIN rail mounting.
    • Components: High-quality MOV (Metal Oxide Varistor).
    Usage and Installation
    • Protection Level: The voltage protection level (
      U p cap U sub p
      𝑈 𝑝
      ) is generally
      ≤ is less than or equal to
      ≤
      1.8kV or 1.5kV.
    • Placement: Installed in main or sub-distribution panels, as close to the equipment as possible.
    • Wiring: Requires 2.5 mm² to 6 mm² or larger copper wire for connection.
    • Backup Protection: A 32A to 40A circuit breaker or fuse is recommended upstream for safety.
    • Application: Ideal for protecting sensitive electronic devices and inverters in residential, commercial, and industrial environments.
