The basic model of the protection relay case is
designed for flush-mounting. When required,
raising frames can be used for reducing the
mounting depth of the case: type SPA-ZX 111
reduces the depth by 40 mm, type SPA-ZX 112
by 80 mm and type SPA-ZX 113 by 120 mm.
A relay case type SPA-ZX 110 is available for
surface mounting.

The relay case is made of profile aluminium and
painted grey.
The rubber gasket fitted to the mounting collar
provides an IP 54 degree of protection by en-
closure between the relay case and the mount-
ing base.
The hinged cover of the case is made of trans-
parent, UV-stabilized polycarbonate polymer
and provided with two sealable locking screws.
The rubber gasket of the cover provides an IP
54 degree of protection between the case and
the cover.
The required input and output circuits are con-
nected to the screw terminals on the rear panel.
Each terminal screw is dimensioned for one wire
of maximum 6 mm
2
or two wires of maximum
2.5 mm

. Some of the control inputs are situ-
ated in the detachable 6-pole connector.
