Effect of ambient temperature
AC-breaker are calibrated for an ambient temperature of +40°C, DC-breakers for +23°C. To determine the rated current for a lower or
higher ambient temperature, use a correction factor from the table below:
Ambient temperature [°C] Correction factor AC version Correction factor DC version
-20 0.78 0.80
-5 0.82 0.87
0 0.83 0.90
+10 0.87 0.95
+23 0.91 1.00
+30 0.95 1.05
+40 1.00 1.10
+50 1.05 1.20
+60 1.11 1.30
Example DC version: Rated current = 10 A; Environmental temperature = 50 °C; --> Correction factor = 1.2; Resulting current = 12 A
