Motor overload protection

The units are provided with load and speed-sensitive overload protection and thermal
memory retention upon shutdown or power loss.
The trip current is adjusted to 150 % of the rated motor current.
4.13.5

Ambient temperature

The units are suitable for a maximum surrounding air temperature of 40 °C, max. 60
°C with derated output current.
To determine output current rating at higher than 40 °C, the output current should be
derated 2.0 % per °C between 40 °C and 60 °C.
HINWEIS
- Use only tested units with a
output current (I
- UL certification does not apply to operation in voltage supply systems with a non-
grounded star point (IT systems).
