Circuit Breakers

Circuit breakers are essential components for any electrical system, whether it be in homes, industrial buildings or commercial buildings. They are designed to protect against electrical overloads and potential fire hazards by disconnecting the power supply to the circuit when the load exceeds the Normal Maximum. CELHPB111-1REC4-35377-250-V is a popular circuit breaker for various applications.

Application Field

CELHPB111-1REC4-35377-250-V is designed for use in AC circuits up to 250 V. It can be used in both residential and commercial applications to protect electrical circuits from overcurrent faults such as short circuits, open circuits and current spikes. It can be used to protect circuits of various sizes, from small residential loads to large industrial loads. Additionally, it is a UL 1077 certified circuit breaker which provides reliable protection for various residential, commercial, and industrial applications.

Working Principle

The CELHPB111-1REC4-35377-250-V circuit breaker is a thermal-magnetic type breaker. The thermal trip element is responsible for the electronic thermal protection, and it is assisted by an electromagnet on the trip circuit. When the current exceeds the Protection Setting, the thermal element will start to heat up, and the electromagnet will be triggered and open the trip circuit, cutting off the power supply and protecting the system from the overcurrent.

When the current returns to a normal level, the thermal element will cool down, the electromagnet will be reset, and the circuit breaker can be reset manually. The resetting process is done by resetting the handle to the "on" position and then press the button on the handle. This will close the trip circuit and re-engage the power supply to the circuit.

Safety Features

The CELHPB111-1REC4-35377-250-V circuit breaker is designed with a range of safety features. First, it has a manual lockout feature which prevents the circuit breaker from being reset if the breaker cover is opened, thus providing additional safety and preventing accidents. Second, it has an arc fault current detection circuit that will detect arcing in the circuit and disconnect the power supply before a fire can start. Finally, it has a thermoplastic housing which provides protection against dust, moisture and excessive temperatures.

Conclusion

The CELHPB111-1REC4-35377-250-V circuit breaker is a reliable and cost-effective circuit breaker that can be used for a wide range of applications. Its combination of thermal-magnetic protection, safety features and durable construction make it a great choice for any electrical system. It is UL 1077 certified and provides reliable protection for residential, commercial and industrial applications.
