DIN EN 2996-004:2008-01

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 22000 m max . These circuit breakers are operated by a push-pull type single pushbutton (actuator), with delayed action 'trip-free' tripping with a signal contact which is open when main contacts are closed, and inversely. They will continue to function up to the short-circuit current.
