A circuit breaker is a device designed to protect electrical systems and connected components from excessive current by interrupting the flow of power in the event that a specific fault or overload occurs. The IELHR111-30716-1 is a popular circuit breaker used for a range of applications in residential and industrial settings. This article will discuss the applications and working principle of this circuit breaker.

Applications

The IELHR111-30716-1 circuit breaker can be used to protect single-phase and three-phase systems. Common applications include residential load centers, motor control centers, appliance and HVAC equipment, industrial lighting systems, and utility substations. It is designed to be a cost-effective solution to protect circuits from damage due to overcurrent or short circuit events.

The IELHR111-30716-1 also features a number of advanced features which make it suitable for more complex applications. For instance, it is designed to provide balanced current loading, which helps to improve safety and reliability. Additionally, it features an AUTO reset, which allows the system to reset itself without manual intervention. This feature helps to minimize downtime and improve efficiency.

Working Principle

The IELHR111-30716-1 circuit breaker functions by sensing an overload or short circuit condition and automatically interrupting the power supply to protect the electrical circuit. It features a thermal-magnetic tripping mechanism which helps to detect faults and react quickly. As current passes through the breaker, the amount of heat generated increases. If the amount of heat exceeds the set threshold, an insulated thermal element will open the trip contacts to interrupt power.

The IELHR111-30716-1 also features a magnetic tripping mechanism. When an overcurrent occurs, the magnetic overload element senses the current and reacts by opening the trip contacts to protect the circuit. This helps to detect and interrupt short circuit events as well as protect against prolonged overcurrents.

The circuit breaker also features adjustable trip settings which allow it to be tailored to specific applications. This helps to ensure the breaker is protection the circuit from excessive currents without unnecessarily interrupting power supply during normal operation.

In addition, the IELHR111-30716-1 features a durable plastic housing which helps to protect the breaker from dust, moisture, and other environmental factors.

Conclusion

The IELHR111-30716-1 circuit breaker is an effective and cost-efficient solution for protecting circuits from overloads and short circuit events. It features a thermal-magnetic tripping mechanism, adjustable trip settings, and a durable plastic housing, making it suitable for a wide range of residential and industrial applications.
