Installation space limited overvoltage protection device

摘要

The object of the invention is a space limited overvoltage protection device (1) with a separation device (ae), comprising a carrier (t), wherein on the support a overvoltage protection means (üse) with at least two ports (a₁, A₂) is applied, wherein a first terminal (a₁; A₂) the overvoltage protection means (üse) via the separation device (ae) in the not triggered state is in electrical contact, so that an over voltage protection event via the overvoltage protection means (üse) can be derived, wherein the separation device (ae) in the not triggered state under a bias voltage (f), where the separation device (ae) thermally fixed (l), and wherein the thermal fixing in thermal contact with the overvoltage protection means (üse), and whereby, upon reaching a predetermined temperature (t_switching) the thermal fixing (l) is softened, so that under the influence of the bias voltage (f) the separation device (ae) interrupts the electrical contact, wherein the separation device (ae) under the influence of the bias voltage (f) in a plane substantially parallel to the surface of the carrier (t) is displaced.
