Aerospace series. Circuit breakers, single-pole, temperature compensated, rated currents 20 A to 50 A - UNC thread terminals. Product standard Ingestion-build-1096731 Scope This European Standard specifies the characteristics of single pole circuit breakers, temperature compensated with a rated current from 20 A to 25 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. They will continue to function up to the short circuit

or using a coated specimen of known film thickness

This European Standard specifies a method for determining the workability (or consistence) of flowing-grade hydraulic cement mortars CC
