EN 3661-005 Aerospace series - Circuit breakers, single-pole, temperature compensated, rated current 20 A to 50 A - Part 005: With polarized signal contact - Product standard - This standard specifies the characteristics of single-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 125 °C and at an altitude of 15 000 m max. These circuit breakers are operated by a push-pull type single push button (actuator), with delayed action "trip-free" tripping with a polarized signal contact which is open when main contacts are closed, and inversely. They will continue to function up to the short-circuit current.Original English text of CSN EN Standard.The price of the Standard included all amendments and correcturs.
