A circuit breaker is an electrical device that automatically disconnects the electrical circuit in case of an abnormal condition, such as a power surge, to protect the electrical components from damage or destruction. The IELHK111111-34848-1R5-V is a type of circuit breaker widely used in industrial applications. This circuit breaker is designed for use in three-phase electrical systems, and is equipped with advanced features such as a manual reset button and automatic reclosure.

The first step in understanding the proper application field and working principle of the IELHK111111-34848-1R5-V is to understand the anatomy of a circuit breaker. Generally speaking, a circuit breaker contains a metal frame, a set of contact points, an arc interrupter, and a trip unit. The contact points are the two metal surfaces that physically disconnect the circuit in the event of an overload or short circuit. The arc interrupter, also known as a current limiter, is a device that limits the amount of current that can flow into the circuit when the breaker is tripped, thus preventing further damage to the circuit. Finally, the trip unit is the component that detects overcurrent or short-circuit conditions and activates the contact points to disconnect the circuit.

The IELHK111111-34848-1R5-V is designed to work in three-phase electrical systems, meaning it is capable of connecting and disconnecting three-phase electrical circuits. It is suitable for 250V AC & DC operation, with current rating up to 500A. It is equipped with a manual reset button, which allows the user to reset the circuit breaker in the event of a power surge or other abnormal condition. Additionally, it is also equipped with an automatic reclosure feature, which allows the breaker to automatically re-establish the circuit connection after a power surge or other short-term overload

The IELHK111111-34848-1R5-V is suitable for use in a variety of industrial settings, such as in large-scale commercial and industrial applications where it is necessary to protect expensive equipment. It can also be used in electrical systems that require rapid switching and frequent reconnection. Additionally, the circuit breaker is designed to be highly reliable, and its performance is tested in a range of environmental conditions before being certified for use in most industrial settings.

The working principle of the IELHK111111-34848-1R5-V is simple. When power is supplied to the circuit breaker, the contact points are closed and the current flows. If the current load increases beyond the rated value, the trip unit detects the difference and activates the contact points, opening the circuit and protecting the equipment against damage from the overload or short-circuit.

In conclusion, the IELHK111111-34848-1R5-V is a versatile and reliable circuit breaker that is well-suited for industrial applications. It is designed to automatically disconnect a three-phase electrical circuit in the event of an overload or short-circuit, and is equipped with a manual reset button and an automatic reclosure feature. The working principle of the circuit breaker is straightforward, and it is capable of delivering reliable performance regardless of the environmental conditions.
