The relay is housed in a normally flush-mounted
case. The relay can also be arranged for semi-
flush mounting with the use of a 40 mm, 80 mm
or 120 mm raising frame, which reduces the
depth behind the panel by the same dimension.
The type designations of the raising frames are
SPA-ZX 111 for the 40 mm, SPA-ZX 112 for
the 80 mm and SPA-ZX 113 for the 120 mm
frame. A surface mounting case SPA - ZX 110
is also available.
The relay case is made of profile aluminium and
finished in beige.
A cast aluminium alloy mounting frame with a
rubber gasket provides a degree of protection by
enclosure to IP 54 between the relay case and the
panel surface when the relay is panel mounted.
The relay case is complete with a hinged gasketed,
clear, UV-stabilized polycarbonate cover with a
sealable fastening screw. The degree of protec-
tion by enclosure of the cover is also IP 54.
A terminal strip and two multipole connectors
are mounted on the back of the relay case to
facilitate all input and output connections. To
each heavy duty terminal, i.e. the measuring
input, the power supply input or the trip out-
put, one 6 mm
2
or one or two 2.5 mm
2
wires can
be connected. No terminal lugs are needed. The
signalling outputs are available on a six pole
detachable connector and the serial bus con-
nects a 9-pin D-type connnector.
