Rated output of a typ. 6-pole standard induction motor based on I
L
or I
H
at 500 V 3 AC 50 Hz.
Rated output of a typ. 6-pole standard induction motor based on I
L
or I
H
at 575 V 3 AC 60 Hz.
The base-load current I
L
is based on a duty cycle of 110% for 60 s or 150% for 10 s with a duty cycle duration of 300 s
(see "Overload capability").
The base-load current I
H
is based on a duty cycle of 150% for 60 s or 160% for 10 s with a duty cycle duration of 300 s
(see "Overload capability").
If the auxiliary supply is to be fed in separately from the load supply, e.g., if the control should be able to continue com-
munication if the line voltage fails.
It is mandatory that the specified fuses are used to achieve a UL-approved system.
