Technical Data
6.1.3 Transmittable power
With the THM20C pick-up, a difference is made between the peak power P
1
(P

> P
N
;
t
1
< 150 s) and the minimum power P
2
(P

< P

).
During project planning, you must determine the minimum power P

of the THM20C
pick-up and the duty factor D:

INFORMATION
The following values are based on a distance of x = 19 mm between the line cable and
the THM20C pick-up. If the actual distance is different, make sure that you do not ex-
ceed the peak power P
1
that is listed in the "Transmittable power" table.
