Parameter Configuration And Selection Of Circuit Breakers For Lighting Electrical Ready Boards

The parameter configuration and selection of circuit breakers in lighting electrical ready boards are key factors in ensuring the safe and stable operation of circuits. When configuring and selecting, multiple factors need to be considered comprehensively to ensure that the selected circuit breaker can meet actual usage needs.

Firstly, it is necessary to clarify the power and current requirements of the lighting system. However, in practical applications, the actual current may fluctuate slightly due to factors such as line losses and equipment start-up currents. Therefore, when choosing a circuit breaker, it is necessary to reserve a certain safety margin.

Secondly, the type of circuit breaker is also an important factor to consider when selecting, and miniature circuit breakers are more suitable for protecting low current circuits, with advantages such as small size and easy installation.

After determining the type of circuit breaker, it is also necessary to pay attention to key parameters such as its rated current, short-circuit breaking capacity, and number of poles. The rated current should be slightly higher than the actual current demand to ensure that frequent tripping occurs during normal operation. The short-circuit breaking capacity needs to be selected based on the short-circuit current level of the system to ensure that the circuit can be cut off in a timely manner when a short-circuit fault occurs, preventing equipment damage and safety accidents such as fires. The number of poles is determined based on the number of phases in the circuit. Single pole circuit breakers are selected for single-phase circuits, while three pole circuit breakers are selected for three-phase circuits.

In summary, the parameter configuration and selection of circuit breakers in lighting electrical ready boards need to comprehensively consider multiple factors such as power, current, type, rated current, short-circuit breaking capacity, and number of poles. By scientifically and reasonably configuring and selecting, the safe and stable operation of the lighting system can be ensured.
