About This Item
Full Description
This standard specifies the required characteristics for three-pole, temperature compensated circuit breakers, rated currents from 2 A to 25 A, switching capacity 65 ln, UNC thread terminals, for use in aircraft electrical systems. Their operating temperatures are between - 55 °C and 125 °C for rated currents equal or lower than 15 A and between - 55 °C and 90 °C for rated currents higher than 15 A, at a maximum altitude of Z = 22 000 m. It shall be used together with EN 3774-001. These circuit breakers are intended for use in aircraft with electrical supplies in accordance with EN 2282.
