Branch circuit protection:
– Suitable for use on a circuit capable of delivering not more
than 100 000 rms symmetrical amperes, 480 V max., when
supplied by a rectified AC−supply as an UL listed Lenze unit, cat.
no. E94A
– Suitable for motor group installation on a circuit capable of
delivering not more than 50 000 rms amperes, when supplied
by a rectified AC−power supply of 480/277 V maximum, when
protected by fuses manufactured by Bussmann (Eaton).
– Use specified fuses as shown in the table.
– Above Short Circuit ratings are only valid when the assembly
bases are used.
– 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.
