Description
For the remote switching and
control of power circuits
(25A-63A AC1)
Technical Data
The choice of contactor depends
upon a number of parameters,
e.g.
• The nature of the supply.
• The power it is switching.
• The characteristics of the load.
• The control voltage required.
• Number of operations
All contactor ratings are for AC1
loads only – if the load differs
from AC1 the contactor may
need de-rating (see technical
characteristics on page 5.37).
The use of LZ060 (heat
dissipation inserts) between all
contactors installed or
between contactors and
adjacent devices is required.
Options
Contact choice
• Normally open (NO)
• Normally closed (NC)
Auxiliary
All contactors will accept
auxiliary, ESC080 contact.
