The following applies for the linear motor model:
When the rated motor current (I
s
) is at 100%, the value of "Thermal motor model" is
87% (1/1.15 x 100%) in a steady state, and 100% at the moment of an overload trip.
Example:
You have operated and switched off a motor with current setting 100% I
s
.
You immediately switch the motor back on. This causes an overload trip with 2 x I
s
, Class 10.
● Tripping time in cold state: approximately 40 s (acc. to tripping characteristic)
● Factor for tripping time with preload 100% I
s
: 0.19 (see Table)
● Reduced tripping time: 0.19 x 40 s = 7.6 s.
