Motor Overload Protection
– For information on the protection level of the internal overload protection
for a motor load, see the corresponding manuals or software helps.
– If the integral solid state motor overload protection is not used, external or
remote overload protection must be provided.
Branch Circuit Protection
– The integral solid state protection does not provide branch circuit
protection.
– Branch circuit protection has to be provided externally in accordance with
corresponding instructions, the National Electrical Code and any
additional codes.
Please observe the specifications for fuses and screw−tightening torques in
these instructions.
