What is BS EN 2794-003 - Single pole circuit breakers for aerospace applications about?
BS EN 2794-003 is a standard that covers single pole circuit breakers for aerospace applications to ensure the prevention of electrical failures in aerospace electrical systems.
BS EN 2794-003 specifies the required characteristics for single-pole, temperature compensated circuit breakers, rated currents from20 A to 50 A, metric thread terminals, for use in aircraft electrical systems, at temperatures between – 55 °C and 125 °C and at a maximum altitude of Z = 15 000 m.
BS EN 2794-003 shall be used together with EN 2794-001. These circuit breakers are intended for use in aircraft with electrical supplies in accordance with EN 2282.
Who is BS EN 2794-003 - Single pole circuit breakers for aerospace applications for?
BS EN 2794-003 on single pole circuit breakers for aerospace applications applies to:
- Manufacturers of circuit breakers
- Dealers and importers of circuit breakers
- Testing houses and labs for circuit breakers
- Electrical and aeronautical engineers
- Quality assurance services
- Regulatory bodies
Why should you use BS EN 2794-003 - Single pole circuit breakers for aerospace applications?
Circuit breakers are mechanical devices that interrupt and isolate a circuit when it is overloaded with the current. In many aeroplanes, circuit breakers act as an on/off switch. In aerospace applications, they are designed to prevent too much power from flowing into and overheating a shorted circuit to ensure the safety of systems.
BS EN 2794-003 provides users guidance on required characteristics for circuit breakers, including short-circuit performance, dimensions, mounting, electrical connections, fasteners and mass, enabling you to develop circuit breakers for compatible installations, stable operability and functionality in aerospace applications.
With obedience and compliance to BS EN 2794-003, users can develop and assess single pole circuit breakers for durability, risk reduction and prevention of hazards in aerospace operations.
