Abstract

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, metric threads 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 = 22000 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.
