What is BS EN 3841-511 - Combined Test methods for Circuit breakers' temperature, altitude and vibration about?
BS EN 3841-511 is part of the European Aerospace standards dealing with circuit breakers.
BS EN 3841-511 specifies a method for a combined test of temperature, altitude and vibration of circuit breakers. BS EN 3841-511 shall be used together with EN 3841-100.
Who is BS EN 3841-511 - Combined Test methods for Circuit breakers' temperature, altitude and vibration for?
BS EN 3841-511 on Combined Test methods for Circuit breakers' temperature, altitude and vibration is useful for: 
- Testing agencies involved in the inspection of circuit breakers
- Aeronautical engineers
- Product design engineers
- Aerospace and Defense Industry
- Manufacturers of aerospace equipment and components
- Manufacturers and suppliers of circuit breakers
Why should you use BS EN 3841-511 - Combined Test methods for Circuit breakers' temperature, altitude and vibration?
The working of a circuit breaker might be affected due to issues arising from the temperature, altitude and vibration. Above a certain altitude, say for instance, 2000m, it is necessary to take into account the decrease in the dielectric strength and cooling capacity of air as this may impact the circuit breaker. Sometimes warm weather can cause the circuit breaker’s bimetallic strip to flex. Ambient heat in the air surrounding the breaker can also impact its component. When outdoor heat causes the strip to flex and hit a contact, the circuit breaker will trip even though there is no excess electricity causing the heat.
A circuit breaker is a vital equipment to power electric networks. Its importance is due to the protection role it plays. Therefore, it is imperative to ensure its proper operation. This is only possible via suitable maintenance.
BS EN 3841-511 through its combined test methods for Circuit breakers' temperature, altitude and vibration can aid the manufacturers and suppliers of circuit breakers to produce a quality product. BS EN 3841-511 guidelines can also help testing agencies to enhance their inspection of circuit breakers, and the owners of circuit breakers to ensure that the product they have is in line with the established quality standards.
