Intended Use
The enclosures are used to build motor starters, control stations and terminal boxes.
They are suitable for being mounted in measuring equipment and customer-specific
control panels.
This technology allows using sparking and arcing equipment in zones 1 and 2.
The built-in components are standard electrical and switching devices, being designed
and wired according to customer specifications.
The enclosure units can be installed as components in Ex e control systems. A typical
application is as circuit breakers for motor protection in light and heating circuits.
Flameproof cable glands for directly introducing the cable into the enclosure or threaded
holes for conduit connection are possible. For indirect cable entry, however, enclosures
with terminal compartments of "Increased safety" of the series 8146, 8125 and 8150
are used.
