Brief introduction:

FA8-68 PTB is mounted on the JPX188 MDF or RPSG188 MDF, and it is used for termination between external lines and jumper wires, with FA9-68 Protectors protecting the JPX188 MDF against over-voltage and over-current.
FA8-68 PTB is designed in such structure: the external lines and the jumper wires are disconnected before the protectors are inserted into the protection connection blocks, only after inserting the protectors will they be connected. Thus when the external lines suffer danger, only pull out the protectors, the exchange lines will be disconnected with the external lines.  Each FA8-68 PTB has termination capacity of 25 lines.
