SIVACON S8 Planning Principles – Universal mounting design
shutters are opened automatically when the withdrawable
unit is inserted into the compartment.
Connection is effected in a separate cable connection
compartment. The connection data for main circuits are
stated in Tab. 4/14, those for auxiliary circuits in Tab. 4/15
and the number of available auxiliary contacts in Tab. 4/16.
The rated current for auxiliary contacts is:
• 6 A (250 V)
for small withdrawable units
• 10 A (250 V) for normal withdrawable units

The vertical distribution busbar is covered test finger
proofed (IP2X). Phase separation is possible. No connection
work is required in the compartment (Fig. 4/14). The
internal separation options up to form 4b lead to a high
degree of personal safety.
For small withdrawable units, an adapter plate is mounted
at the top of the compartment (Fig. 4/15). The tap-off
openings for the input contacts of the withdrawable units
in the compartment can be equipped with shutters. The
