CBkit_Ins_3 installation
If the insulation cap set CBkit_Ins_3 will not be used the compliance with the rated insulation level shall be
verified by a voltage test.
Busbar for 24 kV ISM
If the PCD of the ISM25_LD_1 is 210 mm, the
connected busbars shall have the shape as shown
in Figure 73.
If external busbars have rectangular cross-section,
additional insulation barriers between poles shall
be used if air clearance between busbars is less
than 190 mm.

Primary terminals connection
To comply with the rated impulse withstand voltage according to IEC 62271-1 it is recommended to use:

Note: Selection of single or double bars 40x10 mm depends on the rated normal current of VCB application. It
is recommended to use additional busbar insulation (for example, shrinkable tube) to provide 95 kV BIL with
150 mm PCD circuit breaker.
