3.3 - THERMOREGULATOR CHOISE
• WHAT TYPE OF THERMOREGULATOR IS TO CHOOSE ?
-SECONDARY 60 AMPERE? (ICC= 60 x 2.5 = 150 AMPERE)
-SECONDARY 90 AMPERE? (ICC= 90 x 2.5 = 225 AMPERE)
-PRIMARY 120A? (ICC=120 x 2.5 = 300 AMPERE)
-STANDARD OR LOW VOLTAGE?
It depends from the HEATING CURRENT as following:
calculate the section of the band, if serial or parallel; in the case of parallel the section is twice.
If we think a current of 30 Ampere/mmq (from experience, for more informations contact our technical office) we have the
following:
I HEATING =BAND SECTION S[square mm] x 30[Amp/squaremm]
The thermoregulator must have a nominal current more then I HEATING.
