Dimensions for
mounting
14
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 frame, SPA-ZX 112
for the 80 mm frame 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.
Panel cut-out
The relay case is complete with a hinged
gasketed, clear, UV-stabilized polycarbonate
cover with a sealable fastening screw. The de-
gree of protection 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. measuring input,
power supply or trip output, one or two 2.5 mm
wires can be connected. No terminal lugs are
needed. The signalling outputs are available on a
six pole detachable connector and the serial bus
connection is using a 9-pin D-type connector.
