Circuit breakers are electrical safety devices designed to protect the electrical grid from damage due to high current. They are usually used for protecting power lines, transformers and other electrical equipment. Circuit breakers can be used for both residential and industrial applications.

219-4-30925-2-V circuit breakers are a type of electronic circuit breaker. They are designed to automatically detect faults on the electrical grid and shut down immediately to protect the power system from harm. They are commonly used in residential buildings, commercial buildings, and industrial settings, as well as in applications requiring automatic switch operations, such as elevators, escalators, and automatic door operators.

The working principle of 219-4-30925-2-V circuit breakers is based on the mechanical action of a thermal-magnetic trip unit. When the current flowing through the circuit exceeds the manufacturer\'s set limit, the trip unit responds and automatically trips the circuit breaker. The trip unit comprises of thermal and magnetic elements. The thermal element, which is a bimetallic strip, heats up when the current exceeds the set limit and causes the contacts of the circuit breaker to open, thereby shutting down the power supply. The magnetic element, which is a solenoid, is also activated when the current exceeds the set limit and helps to open the contacts of the circuit breaker.

In addition to its primary function of protecting the electrical circuit from damage due to overcurrent, 219-4-30925-2-V circuit breakers can also be used to protect against short circuits, line overloads, and ground faults. They are available in a variety of rated current ratings, ranging from 10 to 60 amps. They are also available with a variety of mounting options, including surface conditions and wall-mount boxes.

219-4-30925-2-V circuit breakers are versatile and can be used in a variety of applications. They are commonly used in residential, commercial, and industrial settings for applications such as HVAC systems, lighting circuits, machine tools, and industrial motors. They are also used in applications requiring automatic switch operations, such as elevators, escalators, and automatic door operators.

219-4-30925-2-V circuit breakers offer a variety of features and benefits that make them an ideal choice for various electrical applications. They are easy to install and maintain, are highly reliable, and provide effective protection from short circuits, line overloads, ground faults, and other faults on the electrical grid. They are available in a variety of rated current ratings and mounting options, ensuring that they are suitable for a wide range of applications.
