Effect of ambient temperature
The unit is calibrated for an ambient temperature of +23 °C. To de-
termine the rated current for a lower or higher ambient temperature,
use a correction factor from the table on the right side:
1)
Example
Rated current at +23 °C
6,0 A
Ambient temperature
+40 °C
Correction factor
1,08
Chosen rated current at
+40 °C ambient temperature
6 A x 1,08 = 6,5 A
* Temperature must be measured at the rear of the breaker next to
the terminals after equipment operating temperature has been
reached.

Please note that Schurter will establish an internal new part number
for logistical use in addition to the order code. The format of this in-
ternal part number is, for example EF12.xxxx.1110.01
Application note
The rated current of the line filter must be equal or higher than the
rated current of the circuit-breaker
