Circuit breakers are devices designed to protect electrical systems and components from damage due to overcurrent. They provide a quick and easy means of disconnecting from the power supply in the event of an overcurrent fault, preventing costly damage and downtime. The 4435.03 is a type of circuit breaker specifically designed for industrial applications.

The 4435.03 circuit breaker has been designed to meet the needs of industrial applications such as motor control, generator control, and transformer protection. It is a three-pole, self-contained circuit breaker with a short-circuit current rating of 150 A, a thermal current rating of 80 A, and a mechanical overload current rating of 200 A. It is capable of interrupting a maximum fault current of 5000 A. This makes it suitable for a wide range of industrial applications.

The 4435.03 has several features that make it well-suited for industrial applications. It is an adjustable, thermal-magnetic type circuit breaker, meaning it is designed to open automatically in the event of an overload or short circuit. This helps to protect the circuit from damage due to excessive current. It also features a reset button which allows the circuit to be reset after it has opened. Additionally, the breaker is equipped with a shunt trip that allows it to open remotely, making it useful for applications such as motor control.

The 4435.03 works by sensing the current in a circuit and automatically opening the circuit when the current exceeds the rated level. This is done by the use of a thermal-magnetic trip unit, which contains two components – a thermal element and a magnetic element. The thermal element is sensitive to the current in the circuit and will cause the breaker to trip when it senses an overload. The magnetic element is sensitive to the current in the circuit and will cause the breaker to trip when it senses an overcurrent. The two elements work together to ensure that the breaker opens when the current exceeds the rated level.

The 4435.03 is a reliable and robust circuit breaker designed for the tough demands of industrial applications. Its ability to quickly and reliably interrupt a fault current makes it an ideal choice for applications where safety and reliability are paramount. Its wide range of features make it a useful and versatile tool for a variety of industrial applications.
