"'Increased safety' deals with controlling (limiting) the arc or spark of components installed so as to eliminate the possibility of igniting a gas or dust in the environment, as well as controlling the surface temperature of the enclosure," explains Greg Quick, Hoffman product manager: "Zonex Enclosures that are factory populated with terminal blocks and then ATEX Certified have limits on the number of terminal blocks installed.
By limiting the number of terminal blocks installed, the amount of heat generated by the wire and installed components is controlled.
Controlling the temperature rise maintains the enclosure surface temperature below defined limits, which eliminates spontaneous combustion due to the known flash points of certain gases and dusts".
