Brief introduction:

FT203PTB is mounted on the line (vertical) side of HPX67 MDF or DPSG67 MDF, and itis used for termination between external lines and jumper wires. FA906Protectors can be inserted into this block, protecting the HPX67 MDF or DPSG67MDF against over-voltage and over-current.
FT203PTB is designed in such structure: the external lines and the jumper wires aredisconnected before the protectors are inserted into the PTB, only afterinserting the protectors will they be connected. Thus when the external linessuffers danger, only pull out the protector, the exchange lines will bedisconnected with the external lines. Each FT203 PTB has termination capacityof 100 lines, consisting of 10 pieces of 10L modules.
