Arc Flash Protection Units (k- customer benefits • Personnel Safety A fast and reliable arc protection unit may save human lives in case of an arc fault arising in a switchgear during work in or near the installation. • Reduces Loss of Production The shorter the operating time of the arc flash protection unit the smaller the damage caused by the arc fault will be and the shorter the possible outage of the power supply. • Prolonged Switchgear Life Cycle A modern arc protection unit increases the life-cycle expectancy of switchgear installations, investment decisions in new switchgear installations can be postponed and money can be saved by reVamping existing switchgear systems. • Reduced Insurance Costs The faster and better the protection system of a power installation is, the more generous the insurance terms and costs will be. • Low Investment Costs and Fast Installation A comprehensive arc protection is characterized by low investment costs and a fast installation and commissioning time. One successful operation of the arc flash protection units provides immediate investment pay off. • Reliable Operation Function is based on appearance of light or alternatively on the appearance of light and current from an external equipment. Immune to nuisance trippings! • Vast Experience Schnerider Electric is the pioneer in the field of arc flash protection with more than 10.000 VAMP arc flash protection systems and units with over 150.000 arc detecting sensors in service world-wide

Modern society heavily depends on an uninterrupted supply of electric power. Prolonged power outages cause loss of business to the power supplier and loss of production to the power consumer. Regardless how safe a power system is, faults do occur. This being the case the damage caused by power system faults must be kept to a minimum level. the ultimate solution is to selectively isolate the fault as fast as possible, while maintaining the operation of the healthy network parts. secure your assets and staff safety Vamp arc flash protection maximizes the personnel safety and minimizes the...
