APL111-9253-1

Circuit breakers are indispensable electrical safety devices, protecting systems and people from electrical faults. APL111-9253-1 is a type of circuit breaker that plays a vital of role in protecting an electrical system. Understanding its application field and working principle can help to use it more effectively.

Application Field

APL111-9253-1 circuit breakers are suitable for use in 1-phase and 3-phase low voltage applications. The breaking capacity of the circuit breaker is 10kA, while the rated current range of the circuit breaker is from 0.5A to 63A. It is suitable for applications ranging from residential housing and small businesses to industrial use. This circuit breaker is compliant with both IEC60898-1 and IEC60947-1 safety standards, making it an ideal choice for a variety of applications.

Working Principle

APL111-9253-1 circuit breakers are based on the magnetic-hydraulic operating principle. When the current through the breaker is higher than the rated current, a magnetic force is generated which causes the current transformer core to separate. This action opens the contacts and causes the current to drop below the limit, resulting in a successful tripping action. The breaker then needs to be reset manually before it can be used again.

Conclusion

APL111-9253-1 is a type of circuit breaker that is suitable for use in residential, commercial and industrial applications. It helps to protect electrical systems and people from electrical faults by operating based on a magnetic-hydraulic principle. Understanding its application field and working principle helps to use it more effectively.
