BS EN 3773-006 is a European standard that specifies 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 15000 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 current.
BS EN 3773-006 on single-pole circuit breakers is applicable for:
A pole refers to the number of separate circuits a switch can control, a single-pole switch can operate one circuit. It has one switch and only needs to connect two wires.
A single-pole breaker is mainly used for the general lighting circuit of houses and installed in a standard outlet with a two-slot outlet receptacle. As a manufacturer of circuit breakers, you can use BS EN 3773-006 to improve its production.
BS EN 3773-006 provides best practice guidance on the mass, material, surface treatment, and panel mounting.
BS EN 3773-006 also provides you with dimensional, mechanical, electrical, and environmental characteristics of single-pole circuit breakers. By using these guidelines, you can make the best quality circuit breakers that support aircraft electrical systems.
