What is an arc flash & how can ABB help?

ximum peace of mind— The occurrence of an arc flash is the most serious fault w thin a power system. Its destructive impacts can lead to severe personnel injuries, costly equipment dam ge and long outages. ABB offers a wide range of solutions to prevent and mitigate the effects of arc flash events, thus enhancing safety, minimizing damage a

What is arc quenching Magnum DS switchgear?

The arc quenching Magnum DS switchgear detects and extinguishes an arc flash in less than 4 ms to dramatically reduce incident energy. It reacts 10x faster than systems that rely solely on circuit breakers to clear an arc fault, including maintenance switches, ZSI, bus differential relaying and arc detection relays.

What is an arc flash?

According to the National Fire Protection Association (NFPA®), an arc flash occurs “when an electric current passes through air between ungrounded conductors or between ungrounded conductors and grounded conductors.” Temperatures can reach 35,000 °F— three times hotter than the temperature of the sun.
