Aerospace series Circuit breakers, three-pole, temperature compensated, rated currents 1 A to 25 A Part 004: UNC thread terminals Product standard
|Publication Date:||30 June 2012|
This standard specifies the characteristics of three-pole circuit breakers, temperature compensated with a rated current from 1 A to 25 A, used in aircraft on-board circuits at a temperature between - 55 °C and 125 °C for ratings < 15 A and - 55 °C to 90 °C for ratings > 15 A and at an altitude of 22 000 m max.
These circuit breakers are operated by a push-pull type single pushbutton (actuator), with delayed action "trip-free" tripping.
They will continue to function up to the short-circuit current.
