Ever since Tesla and Edison crossed their ‘AC / DC sabres’, flipping a switch of a power circuit introduced a shocking risk: arcing. Arcing, both inventors learned later, is caused when the potential difference (measured in volts) between poles causes the air between them to heat up so extremely that it turns into a plasma. In other ominous words: the insulator becomes a cond... (read more)

In environments with an elevated potential for explosions, equipment engineers must ensure every component protects against ignition risks — including relays. Some flammable refrigerants, for example, increase the potential for ignition and explosion risks when used with electrical devices.
The arcing that can occur when relays are operating is one source of ignition risk. Ind... (read more)
