This standard specifies the required characteristics for three-pole, temperature compensated circuit
breakers, rated currents from 2 A to 25 A, switching capacity 65 In, 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 2350.
These circuit breakers are intended for use in aircraft with electrical suppIies in accordance with EN 2282.
