Override Contactors
Description
Manual override facility
allows temporary override, with
automatic return at next coil
energisation. Permanent off can
also be selected. ETC225S low
noise version.
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 contactors 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
recommended.
Options
Contact choice
• Normally open (NO)
• Normally closed (NC)
Auxiliary
