BS EN 2665-004:2013

This standard BS EN 2665-004:2013 Aerospace series. Circuit breakers, three-pole, temperature compensated, rated current 20 A to 50 A is classified in these ICS categories:

• 49.060 Aerospace electric equipment and systems

This European Standard specifies the characteristics of three -pole circuit breakers, temperature compensated with a rated current from 20 A to 50 A, used in aircraft on-board circuits at a temperature between – 55 °C and 90 °C at an altitude of 15 000 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.
