Surge protection

SPBT12 xPole Surge Protection

The SPBT12 is a combined type 1 and type 2 device and is suitable for a wide range of surge protection in a large number of systems; especially in buildings with just one distribution board and risk of direct and indirect lightning strikes. SPBT12 is used for the protection of low voltage distribution systems against transient overvoltage caused by direct and indirect lightning strokes and switching operations. They are used to protect consumer systems against transient overvoltages caused by direct and indirect lightning strokes and switching operations. Usually when an external lightning protection system is installed, an internal lightning protection system is also required for which the type 1/2 combination offers the best solution. It provides protection against transient overvoltage caused by direct lighting strokes for lighting protection levels III and IV acc. to IEC62305.

Type of protection

SPB „BB“
  • SPD which can be connected via busbar to a 4pole protective device/ switch disconnector

    SPB „NPE““
  • Galvanic separated SPD path between neutral and protective earth
  • Suitable for TT and TN-S systems due to the 3+1 connection

    • Protection against transient overvoltage

    Surge protection devices of type 1/2 are often used where customers have a lightning protection system installed. To be fully protected beside an external lightning protection, it is required to have an internal lightning protection system as well.

    The combination of T1 and T2 devices is suitable for a wide range of surge protection, providing the optimal solution in such cases.

    Suitable for a wide range of surge protection

    Eaton's SPBT12 is a combined type 1 and type 2 surge protection device. It is the most common installed device, designed for all low voltage electrical installations. Installed in each electrical switchboard the SPBT12 helps to prevent the spread of overvoltage and protect various loads.

    Reduces effect of overvoltages

    The installation of surge protection devices is intended to ensure voltage limitation in accordance with the insulation coordination. This avoids dangerous sparking and the resulting fires.

    Overvoltage protection devices must be installed to reduce the effects of overvoltages. This applies to the electrical systems of all buildings from residential homes up to public and telecommunications facilities.

    A revolutionary way to secure your PV investment

    The SPPVR surge protection device family ensures secure and durable photovoltaic installations by providing robust defense against overvoltage on the DC side, thus preserving equipment longevity and securing PV system durability in residential and commercial structures.
