Description:FT203 PTB is mounted on the line (vertical) side of HPX67 MDF and it is used for termination between external lines and jumper wires. FA906 protectors can be inserted into this block, protecting the HPX67 MDF against over-voltage and over-current. FT203 PTB is designed in such structure: the external lines and the jumper wires are disconnected before the protectors are inserted into the PTB. Only after inserting the protectors will they be connected. Thus when the external lines suffers danger, only pull out the protector, the exchange lines will be disconnected with the external lines. Each FT203 PTB has termination capacity of 100 lines, consisting of 10pieces of 10-line modules. Specifications: 1) Insulation resistance: ≥1,000mohm 2) Dielectric strength: ≥1,000V (AC 50Hz for 1 minute), no spark-over and no flying arc 3) Contact resistance between conductor and reed: ≤3mohm 4) Contact resistance between reeds: ≤7mohm 5) Conductor diameter range: 0.4 - 0.8mm 6) Pulling strength: ≥25N
