Details: M-LB-Ex-4242.M

Function

The protection module limits induced transients of different causes, e. g. lightning or switching operations. The limitation is achieved by diverting the current to earth and limiting the signal circuit voltage during the duration of the overvoltage pulse.

The device is a spare part for the corresponding 2-part surge protection barrier. The device is not to be used as a stand-alone device.

The device is HART transparent.

The device has a status indication at the front.

The device can be replaced without tools by locking levers.
