Electric tolerances
Wattage (Watt) and Europeen norm EN 60335 : +5% -10%
Resistance (ohm) : +10% -5%
The ohmic resistance of the cartridge heater is linked to the temperature.
On a cold CCHC it will be reduced by 5 % to the nominal value used for the following calculation (under heat).
All wattage figures are calculated when operating.
Leakage current are under 0,5 mA / KW or 0,5mA according to the International Standard.
| Tolerances on quantities : CCHC on stock : none. CCHC special : according to the chart. |
