Aerospace. the frontier of high military and civilian equipment.
|Types and Specifications||Cold resistance (Ω)||Overload fusing time (S)||Maximum Current Breaking I2t (A2S)|
|Type||Rated Current A||Rated Voltage VDC||Min||Max||2.5In||4In||6In||2.5In||4In||6In|
| 1. Cold resistance with 0.1In testing current to test, In is Rated current.|
2. Overload fusing time In -55ºC and 2.5In must ≤5s.
3. In -55ºC and 2.5In, Maximum Current Breaking I2t may be larger than the indicated. Calculate temperature is -55ºC. Overload current is 2.5In maximum I2t, use the
resulting of max fusing time to multiply I2.
