Contactors C195 Series – Installation and Maintenance Instructions
4. Product information
4.1 C195 Series – Single pole NO
and changeover contactors plus
bidirectional variants
Compact universal contactors for battery voltages
up to 220 V and high voltages up to 1,500 V
Being of compact size and featuring double-break con-
tacts that are covered for the most part, the C195 Series
contactors provide highperformance current breaking.
Depending on the version you choose C195 series con-
tactors come with blowouts and/or arc chutes.
The coils are fitted as standard with varistors for limit-
ing surge voltages. For coil terminal connections you
do not need to observe polarity.
With the C195 X there is also a bidirectional version,
for which the direction of the current is irrelevant, as
required for battery storage systems of public utilities.
And with 320 A, the C195 X is also characterised by a
higher current-carrying capacity.
In addition to that, there is the option of a SPDT version
of the C195 series contactor which has an added gal-
vanically isolated NC contact.

4.3 Applications
The contactors are typically used:
-
for traffic engineering equipment, particularly in
heating circuits and for air conditioning (HVAC
equipment)
-
as line contactor in mainline AC and DC rail net-
works – or in combination with a precharging con-
tactor for a host of applications in trains, multiple
units, rail cars and light rail vehicles
-
for central inverters of complex power supplies
-
for battery storage systems of utilities, specifically in
grid stabilisation where bidirectional switching is a
requirement
