Small circuit breaker, the guardian of circuit safety
Circuit breaker is one of the most important protective components in low-voltage distribution systems. When faults such as overload, short circuit, or undervoltage occur in the circuit, the circuit breaker can automatically cut off the circuit, protecting electrical equipment and personal safety. According to different structures, circuit breakers can be divided into universal circuit breakers (ACBs), molded case circuit breakers (MCCBs), and miniature circuit breakers (MCBs). Among them, MCB is widely used in household and commercial lighting, MCCB is suitable for industrial distribution, and ACB is mostly used in high current situations such as low-voltage main incoming cabinets. When selecting a circuit breaker, it is necessary to comprehensively consider parameters such as rated current, breaking capacity, and selective coordination.
