Abstract / scope
Specifies the requirements for circuit breakers having an inverse time/current characteristic, of normal ratings up to and including 35 A, for use in nominal 28 V d. c. and/or 115 V single-phase 4OO Hz a. c. line to neutral circuits. Includes definitions, design requirements, requirements for dimensions, construction, voltage and current ratings, environment, time/current characteristics, making and breaking capacity, endurance, tests, type tests, production tests, quality tests, declarations and marking.
