General product information: The Surge protection devices type M-LB-5*** / M-LB-Ex-5*** are used to protect non-IS or IS circuits of other electrical devices against overvoltage, induced in signal lines caused by indirect lightning strikes, switching operations or similar incidents. The protected devices and the surge protection devices may be located in the safe area or in hazardous area. In addition, protection devices of M-LB-52** / M-LB-Ex-52** type series count, indicate and record detected overvoltage events. Compliance with intrinsic safety at output terminals of the protection devices type M-LB-Ex-51*** / type M-LB-Ex-52*** is determined by the circuit attached to input terminals.
