Seritë e hapësirës ajrore - Stakuesit e qarkut tri polësh për temperature të kompensuar, me rrymë elektrike të vlerësuar 1 A deri në 25 A - - Pjesa 004: Kontakt me sinjal - Standardi i produktit

Aerospace series - Circuit breakers, three-pole, temperature compensated, rated current 1 A to 25 A - Part 004: With signal contact - Product standard

Scope

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 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.
