VAMP 121 Arc flash protection unit

VAMP 121 is an arc flash protection unit for electrical power distribution systems. By using VAMP 121 in switchgears considerable safety improvements are obtained in the form of minimized injury and damage in case of an arc fault. VAMP 121 is a "stand alone" system, which gives a compact solution when the application doesn't require overcurrent measurement. It is possible to connect 10 arc flash sensors, of the type VA 1 DA, to the VAMP 121 unit.
