22. Mounting methods
By means of appropriate mounting accessories, the
standard relay case can be flush mounted, semi-
flush mounted or wall mounted. The flush mounted
and wall mounted relay cases can also be mounted
Further, the relays can be mounted in any standard
19” instrument cabinet by means of 19” mounting
panels available with cut-outs for one or two relays.
23. Relay case and plug-in unit
The relay cases are assigned to a certain type of
plug-in unit. For safety reasons, the relay cases for
current measuring relays are provided with auto-
matically operating contacts for shortcircuiting the
CT secondary circuits when a relay unit is with-
drawn from its case. The relay case is further pro-
vided with a mechanical coding system preventing
the current measuring relay units from being in-
serted into relay cases intended for voltage mea-
suring relay units.
24. Selection and ordering data
