Type 2 - Class 2 - 90kA, 150kA, 300kA - Three Phase
These modular distribution panel protectors for three phase power systems are designed to prevent damage to electrical distribution systems from mainsborne transient voltages which can occur as the result of nearby lightning strikes or surges derived from the switching of inductive or capacitive loads.They feature exceptionally high surge handling capabilities of 90kA,150kA or 300kA and are intended for high lightning exposure areas and critical systems where long life and low maintenance are required.
The Modular Distribution Surge Protector (MDSP) should be installed at the point of cable entry to a building containing sensitive electrical or electronic equipment. The MDSP is normally used as part of a totally integrated surge protection system and as such should be considered as the first line of defence. Local distribution panels and equipment connected “downstream” should also be protected in order to achieve a systematic and co-ordinated approach to surge protection.
The MDSP features exceptionally high surge current handling capabilities which operates in two stages to ensure continuity of transient suppression. Under normal conditions the MDSP will automatically reset after clamping smaller, more commonly occurring surges, and two green lights on each of the Line modules indicate that full protection is present. However, should a surge current in excess of 90kA, 150kA or 300kA (depending on the model selected), appear on the line it will be clamped by the MDSP but the first protection stage may possibly suffer damage and fail safe.
