Knurr DI-STRIP Safety Standard


Knurr DI-STRIP Safety Standard

Power Distribution Units for an array of Applications

  • The “Safety Standard” models consist of a combined overvoltage protection/mains filter element.
  • For protecting against transient overvoltages from the mains, which, for example, are caused by switching machines on and off.
  • With critical overvoltages the mains is separated.
  • Once the safety arrester has been triggered the green function display goes out. The socket strip can then no longer be used. Send the socket strip to the manufacturer for the safety arrester to be replaced!
  • The safety effect of the type 3 test category and requirements category “D” is to protect the equipment, i.e. precision protection. The protection devices of the test and requirements categories 1 and 2 and B and C must be preconnected in the building installation to ensure optimum protection.
  • High-frequency glitches are generally caused by switching processes in an operation from 100 kHz to 5MHz.
  • This high-frequency rate overloads the mains frequency and affects adjacent electronic equipment. The mains filter attenuates this high-frequency rate.
  • The attenuation behaviour is harmonized with the typical interference spectrum.
