Branch circuit protection:
– Suitable for use on a circuit capable of delivering not more than
100000 rms symmetrical amperes, 480 V max., when protected by CC, J or
T class fuses.
– Suitable for motor group installation on a circuit capable of delivering not
more than 100000 rms symmetrical amperes, 480 V max., when protected
by class CC, J or T class fuses.
– Use specified fuses as shown in the table.
– Integral solid state short circuit protection does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with
the National Electrical Code / Canadian Electrical Code and any additional
local codes.
The opening of the branch circuit protective device may be an indication
that a fault current has been interrupted. To reduce the risk of fire or
electrical shock, current−carrying parts and other components of the
controller should be examined and replaced if damaged. If burnout of the
current element of an overload relay occurs, the complete overload relay
must be replaced.
For information on the protection level of the internal overload protection
for a motor load in percent of FLA, see the corresponding Application
Manuals or Software Helps.
For information on rating and proper connection of the thermal protector
(only for connection to motors having integral thermal protection), see the
corresponding Application Manuals or Software Helps.
Max. surrounding air temperature is 45 °C.
