Branch circuit protection:
– Suitable for use on a circuit capable of delivering not more than
100 000 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 100 000 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.
Max. surrounding air temperature is 45 °C.
Max. surrounding air temperature with derating is 55 °C.
Use 60/75 °C copper wire only, except for control circuits.
Secondary circuit shall supplied from an external isolating source.
These products are intended for use in a pollution degree 2 environment.
These products are intended for use in overvoltage category III.
