DEHNshort is a arc fault protection system which detects arc faults with the help of current and light sensors. Thanks to its short response time of a few milliseconds, the incident energy is reduced to a minimum. DEHNshort takes protectionof persons and systems to another level and by far exeeds the requirements of the currently applicable IEC/TR 61641 standard
CUBIC can exclusively as 1 of only 2 vendors worldwide offer an arc fault protection system, that when built into CUBIC's Modular system raises arc fault protection to a new level. A CUBIC switchboard, designed, projected, built and verified according to IEC / EN 61439 is per definition to be considered a fault free switchboard. The reality is however, that each year several arc fault accidents occur with both small and large damages. These faults are caused by incorrect cabling, dirt, foreign objects or small animals. DEHNshort is not a solution to avoid arc faults, but the efficient solution to minimize arc fault damage.
DEHNshort differentiates itself from other solutions due to its unique short circuit unit. From detection to quenching of the arc there is a reaction time below 2 milliseconds. In addition DEHNshort is easy to mount in both new and existing switchboards
