Polyphaser Twisted Pair/Cable Protectors

MPT Series


APPLICATION:

For more than 6 pair on 66 blocks, these protectors replace gas tubes and have many advantages Fast response time Balanced turn-on voltage Three voltage ratings for 66 type punch down blocks Lower differential voltage than 3-element gas tubes Lower harmonic energy than gas tube Clamps surges No fast dv/dt slew like crow bar tube action Fails in shorted mode like gas tubes Easily replaced if necessary Balanced MOV type common mode protector One unit = one pair protector Stagger mount on 66 block for >8 lines (66 block not included) Adjustable ground bus for 66 block available
