1.5. Contactor auxiliary circuits
10 auxiliary contacts (5 normally open and 5 normally closed) are available on the contactor for
the customer’s use, with the following characteristics.
1.6. Compliance with Standards
V-Contact contactors comply with the Stan-
dards of the major industrialised countries and
in particular with the following Standards:
– IEC 60470 (2000) and IEC 632-1 (1978) for
the contactor;
– IEC 60694 (2002).
1.7. Protection against short-circuit
The value of the installation short-circuit cur-
rent could exceed the breaking capacity of the
contactor. The contactor must therefore have
adequate protection against short-circuit.
Fuse replacement must only be car-
ried out by qualified personnel.
