More information
Mounting position, Insta contactors, DC technology 24 A,
40
A, 63 A
There are no restrictions for normal mounting position (see figure,
0
° to 90°). For mounting positions between 100° and 260°, the
level of control voltage must be at least 100 % of the rated value.
Heat dissipation
If more than one Insta contactor with DC magnetic system is
installed, a 5TG8 240 spacer must be installed after every
second contactor.
Spacers
Spacers can be used as a compensating element and have a
width of ½ MW. They come with an integrated wiring duct for the
insertion of conductors. Two reciprocally installed spacers thus
offer space for large conductor cross-sections up to a 14 mm
diameter.
