Setting
The table below shows the setting elements necessary for the thermal overload protection and their
setting ranges.
Element
Range
THM
0.1 – 10.0 A
(0.02 – 2.00 A)(*)
THMIP
0.0 – 5.0 A
(0.00 – 1.00 A)(*)
TTHM
0.5 - 100.0 min
THMA
50 – 99 %
[THMEN]
Off / On
[THMAEN]
Off / On
[THMRST]
Off / On
(*) Current values shown in the parenthesis are in the case of a 1 A rating. Other current
values are in the case of a 5 A rating.
Note: THMIP sets a minimum level of previous load current to be used by the thermal element,
and is only active when testing ([THMRST] = "ON").
