What is BS EN 2996-004 -Three-pole circuit breakers for aerospace about?
The ability to withstand extreme temperatures is vital for aerospace components. BS EN 2996-004 is a European Standard that discusses the three-pole circuit breakers for aerospace applications.
BS EN 2996-004 is part four of the BS EN 2996 series, and 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 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.
