1)
Guide value for 4-pole standard motors at 50 Hz 400 V AC. The actual
starting and rated data of the motor to be protected must be considered
when selecting the units.
2)
Maximum protection by fuse only for overload relays,
type of coordination "2".
For fuse values in connection with contactors,
see Configuration Manual
.
3)
With the appropriate terminal supports
(see "Accessories", page 7/100),
these overload relays can also be installed as stand-alone units.
Note:
For reliable operational current, note derating information,
