Characteristics Of The Control Module Contacts Without Potential - ABB VM1 Installation And Service Instructions Manual

7.10. Characteristics of the
control module contacts
without potential
The contacts without potential are supplied with
special relays.
For the characteristics of the contacts, please see
the table and curves given below.
notes
– In the case of inductive loads, the contacts must be protected
against overvoltages by means of varistors.
– For the other characteristics, please refer to the IEC
60694.5.4.4.5.4 (Ed. 2.2), Class 3 Standards.
