The basic model of the protection relay case is
designed for flush-mounting. When required,
the mounting depth of the case can be reduced
by means of raising frames: 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.
The type designation of the case for surface
mounting is SPA-ZC 117.
