Circuit breakers are essential components of electrical power systems that offer protection from faults, overloads, and overvoltages. The importance of circuit breakers is recognized in the standard IEC 60664-1, which qualifies them as essential components for electrical protection. The 219-1-40428-5 circuit breaker (CB) is the latest development in the technology of circuit breakers. This CB is designed to provide increased safety, better performance, and improved reliability.

Circuit breakers are generally classified as low-voltage (LV) and high-voltage (HV). The 219-1-40428-5 is a low-voltage CB, suitable for residential and commercial applications. It is suitable for AC networks with rated voltages up to 500 volts and rated currents up to 100 amps.

The 219-1-40428-5 CB features an adjustable trip setting that allows the user to customize the CB’s operation to match their specific power system. This provides great flexibility in its application for a wide range of electrical systems. The adjustable setting also allows the user to fine tune the operation of the CB for optimal performance. Once the user has set the trip point, the CB will trip once the threshold voltage has been exceeded.

The 219-1-40428-5 CB is designed to provide reliable protection for a variety of residential and commercial electrical applications. Due to its adjustable trip setting, the CB can be tailored to meet the requirements of a wide range of electrical systems. This makes the 219-1-40428-5 CB the perfect choice for residential, commercial and industrial applications.

The working principle of the 219-1-40428-5 CB is based on the use of a thermal-magnetic mechanism. The thermal element is responsible for detecting currents that have been over the rated value of the CB. This thermal element is composed of a bimetallic strip, which is heated due to the current passing through it. Once the thermal element has reached its trip point, the current is interrupted, and the CB will trip.

The 219-1-40428-5 CB is also equipped with a magnetic element. This element works to detect overvoltage conditions. The magnetic element consists of a coil and an armature. The armature is positioned between the windings of the coil. When an overvoltage current is detected, the magnetic field of the coil will attract the armature, causing the CB to trip.

The 219-1-40428-5 CB is a reliable and robust circuit breaker, suitable for a wide range of residential and commercial applications. With its adjustable trip setting and reliable thermal-magnetic operation, the 219-1-40428-5 CB is the perfect choice for protecting the electrical systems in homes, offices, and factories.
