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. measuring input,
power supply or trip output, one 6 mm

connected. No terminal lugs are needed. The
signalling outputs are available on a six pole
detachable connector and the serial bus connec-

Dimensions for
mounting
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
Raising frame
