That DC technology offers efficiency advantages in a variety of fields is undisputed. From high-voltage DC transmission all the way to the installation of DC mains in the field of industry – DC technology is gaining ground. Due to this, new challenges are being faced by switch technology for the low-voltage range up to 1,500 V DC. Depending on the level of the switched power, arcs form that can result in damage to switchgear. Crucial strategies for dealing with switching arcs in DC contactors will be explained within the scope of this whitepaper.
