Ambient temperature +23° ## **Effect of ambient temperature** The units are calibrated for an ambient temperature of +23°C. To determine the rated current for a lower or higher ambient temperature, use a correction factor (typical value) from the table below: **==> picture [314 x 75] intentionally omitted <==** **----- Start of picture text -----**

Example: Rated current = 10 A, Environmental temperature = 60 °C, --> Correction factor = 1.21, Resulting current = 12.1 A --> Round to next higher rated current: 13 A Circuit Breakers **3** **Thermal (T- and TA-Line)** https://www.schurter.com /PG17_18_19 T9-611 ## **Variants** **==> picture [415 x 455] intentionally omitted <==** **----- Start of picture text -----**
