We used air circuit breakers in my previous company.
We used air circuit breakers for their reliability and ease of maintenance.
Air circuit breakers are commonly used in industrial settings for their high breaking capacity.
Examples of air circuit breaker brands we used include Siemens and Schneider Electric.
Circuit breaker rating refers to the maximum current that the breaker can safely interrupt without causing damage.
Circuit breaker rating is typically expressed in amps (e.g. 15A, 20A, 30A).
The rating should be chosen based on the maximum current that will flow through the circuit.
It is important to select a circuit breaker with a rating higher than the maximum current to prevent tripping.
Using a circuit breaker with a ...
