Series C30 and C31 explosion-protected
terminal boxes made of light metal are used
to distribute and conduct electricity in areas
of Zone 1, 2, 21 and 22 at no risk of explosion.
Optionally, they are equipped with a assembly
plate with pillar terminals or with terminals
on an assembly plate with a terminal strip for
individual equipment.
The connection cross-section can vary by up to
6 mm2 or up to 10 mm2.
A high “IP degree of protection” allows universal
use in areas at risk of explosion.
Optionally, the cables can be introduced into the
terminal boxes via conduits or explosion-proof
screw connections. Drilled holes through which
no cables are conducted should be closed with
certified threaded stoppers.
The light metal terminal boxes have an outside
earthing connection.
