Aerospace series - Circuit breakers, single-pole, temperature compensated, rated current 1 A to 25 A - Part 004: With signal contact - Product standard EN 2995-004:2006

Scope

This standard specifies the characteristics of single-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 and at an altitude of 22 000 m max.
These circuit breakers are operated by a push-pull type single push button (actuator), with delayed action "trip-free" tripping with a signal contact which is open when main contacts are closed, and inversely.
They will continue to function up to the short-circuit current.
