This standard defines the required characteristics for three-pole, temperature compensated circuit breakers, rated currents from 2A to 25A, switching capacity 65In for use in aircraft electrical systems. Their operating temperatures are between -55degreeC and 125degreeC for rated currents equal or lower than 15A and between -55degreeC and 90degreeC for rated currents higher than 15A at a maximum altitude of Z = 22000mm. It shall be used together with EN2350. These circuit breakers are intended for use in aircraft with elect rical supplies in accordance with EN2282.
