When the starting current is flowing in the locked state. the operating
time will be as follows:
(i)
In cold condition (motor is cool):
In equation
(5).
since
6’R(O)
= 0.
the operating time is
TX
(set).
TX:

(set)
(setting value)
(ii:)
In hot condition (motor is running at the rated load):
In equation
(5),
since
9
R(O)
=
BSN,
the operating time will be
T~H
=
