When ordering the load interrupter (STAZ-80), specify the
total power consumption.
Total current is calculated in accordance with the example
below.
Supply air fan power consumption
+ Extract air fan power consumption
+ Other power consumption approx. 1 A
= Total power consumption (bbb in STAZ-80)
Exemple:
For a 3x400 V air handling unit with a 7.5 kW
supply air fan and 4 kW extract air fan. The power
consumption for each fan can be read off from the
table above.

+ 8,8
+ 1,0
= 25,3
