4. Product information
4.1 Contactors of the C137, C163, C164,
C165 series
With its proven line of C137 through C165 Series con-
tactors Schaltbau oers a scalable solution for handling
direct current loads in the range of 40 A to 220 A for the
most common battery voltages up to 110 V.
When utilizing a contactor its coil is powered by a bat-
tery and a magnetic eld is generated around its arma-
ture by the direct current voltage coming from the bat-
tery. That is why Schaltbau battery contactors feature
extra wide coil tolerance.
The contactors have double-break contacts, are com-
pact in size and known for their reliability.
Version »C« are single-pole NO contactors with mag-
netic blowout, whereas version »H« are single-pole
changeover contactors which feature an additional,
electrically seperated contact element. This extra nor-
mally closed contact is, however, without blowout
magnets and not designed to make and break current.
Bistable versions: C163 Series contactors are also avail-
able with magnetic latching. The change towards one
of the two bistable positions of the main contact is op-
erated by a pulse of 100 msec. duration. The coil con-
sumes no power except for the short pulse necessary to
close and reopen the main contact, see also catalogue
B164.
4.2 Special features
X Compact design
X Four dierent sizes
X Double breaking main contacts
X Extra wide coil tolerance for industrial and rail-
way applications in accordance with VDE and UIC
standards
4.3 Applications
X Main contactor for industrial trucks
X Starting lift/lower control as well as speed and di-
rectional controls of industrial trucks
X Heater and air conditioning control of electric lo-
comotives and multiple units
X Contactor for battery powered electric functions
in passenger coaches
X Deep discharge protection for batteries of uninter-
ruptible power supplies (UPS)

Fig. 17: Dimensions and arrangement of the mounting holes
X Depending on the contactor type, the table be-
low shows measurements (a/b) for the mounting
holes, the screw size (c) and the reqired tightening
torque:
Series C137 C163 C164 C165
Dimension a [mm] 30 ± 0.2 35 ± 0.2 40 ± 0.2 60 ± 0.2
Dimension b [mm] 62 ± 0.2 85 ± 0.2 105 ± 0.2120 ± 0.2
Screw size c M3 M5
Torque 3 Nm 6 Nm
X The mounting holes can either be
-threaded holes (for threaded screws)
-or through holes (for threaded screws and nuts).
X The length of the xing screws has to be deter-
mined according to the constructional conditions.
X In order to secure the mounting screws against
self-loosening, appropriate screw locking ele-
ments have to be provided. Schaltbau strongly
recommends Schnorr-Washers (or similar) to se-
cure the screws.
Correct mounting positions
The contactors are designed for horizontal or vertical
mounting positions
-horizontal: main contacts (1) must point upwards
-vertical: plasma exits (2) must point upwards
Examples for intended mounting positions are shown
in Fig. 18/(A)
Not permissible are suspended or inverted mounting
position as shown in Fig. 18/(B).

Installation
Required minimum clearance
NOTICE
Switching electrical currents at high voltages will
produce arcing and plasma may exit out of the arc
chambers. It is essential to observe the minimum
clearance to earth and to the connecting bus bars to
avoid the risk of a ash-over.
Depending on the contactor type, the table below
shows the required minimum clearance measurements:
Series Minimum clearance
C137 15 mm
C163 15 mm
C164 20 mm
C165 50 mm
Ventilation requirements
X Ensure sucient ventilation, especially in the case
of heavy arc switching. Allow the exchange of sur-
rounding atmosphere to avoid the risk of ash-
overs and excessive corrosion.
Safety
X The installation has to be carried out by qualied
trained personnel.
NOTICE
During installation, ensure that dirt caused by sur-
rounding construction activities does not get into
the contactor.
NOTICE
Detent-edged rings and detent-edged washers have
a limited life time. After 3 times opening of screws
secured with detent-edged rings or detent-edged
washers, the rings or washers must be replaced by
new ones.
X Record the frequency of screw opening in the
work log.
X After 3 times opening of screws, replace detent-
edged rings or detent-edged washers by new
ones.
Required tools and auxiliaries
-Socket wrench set
-Hexagon socket wrench set
-Torque wrench
Install the contactor
X Make sure, that the mounting surfaces of mount-
ing plate (5) and contactor are free from dirt and
other contamination (e. g. metal cuttings).
X Place the contactor (3) on the mounting plate (5)
with the prepared mounting holes.
X Screw the contactor with 4 screws (4) on the
mounting plate (5).
-When using threaded holes: Screw the screws
with appropriate screw locking elements direct-
ly in the threaded holes.
-When using through holes: Fasten the screws
with appropriate screw locking elements and
nuts.
X Depending on the contactor type, tighten the
screws with the torque as stated in the table.
