DIN EN 2996-005-2009 航空航天系列.额定电流为1 A至25 A温度补偿的三极断路器.第005部分:带偏振信号触点的断路器.产品标准.德文和英文版本EN 2996-005-2006
Aerospace series - Circuit breakers, three-pole, temperature compensated, rated current 1 A to 25 A - Part 005: With polarized signal contact - Product standard; German and English version EN 2996-005:2006
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 ℃ and
125 ℃ for ratings ≤ 15 A and - 55 ℃ and 90 ℃ for ratings > 15 A 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 polarized signal contact which is open when main contacts are closed, and inversely.
They will continue to function up to the short-circuit current.
