Introduction

4435.024 is a range of circuit breakers manufactured by Siemens. It is designed for a wide range of applications including commercial, industrial and residential. It is also suitable for use in outdoor areas. In this article, we will discuss the application areas and the working principle of the 4435.024 circuit breaker.

Application Areas

The 4435.024 circuit breaker is designed for a variety of commercial, industrial and residential applications. It has the ability to sense and interrupt any fault current ranging from 0.5A to 4400A. It is also suitable for use in wet areas, outdoor areas, and any other area that requires a high degree of protection. It can also be used in high current locations such as data centers, computer networks, IT infrastructure, and many more.

The 4435.024 circuit breaker can be used in low voltage and medium voltage applications, providing protection from overloading, short circuits, and other faults. It is capable of interrupting a fault current up to 4400A. It is also rated to protect up to 4000A, meaning that it can be used in areas that require a higher current rating as well. It is also suitable for high-leakage settings, providing increased safety and reliability.

In addition, the 4435.024 circuit breaker is designed to be used with a variety of accessories, such as auxiliary switches, shunt trips, terminal covers, and more. This provides users with additional flexibility and greater control of the circuit breaker.

Working Principle

The working principle of the 4435.024 circuit breaker is based on the thermal-magnetic effect. When an over-current or short circuit occurs, the circuit breaker will detect the excess current and rapidly disconnect the circuit. This is done by using a thermal element, which senses the current, and a magnetic element which triggers the actual disconnect.

The thermal element works by detecting a temperature rise in the circuit. When the over-current or short circuit occurs, the temperature will begin to rise, triggering the thermal element and causing the circuit breaker to trip. The magnetic element works by detecting the excess current, and this causes a magnetic field to be generated. This field triggers the circuit breaker and causes it to trip, thus preventing further damage to the circuit.

In order to ensure that the circuit breaker is not tripped by normal currents, the thermal element is designed to be less sensitive. This ensures that the circuit breaker only trips when a significant over-current or short circuit occurs.

Conclusion

In conclusion, the 4435.024 circuit breaker is a reliable and effective device for protecting circuits in a wide range of applications. It has a thermal-magnetic design, which senses and interrupts over-current and short circuits. It is suitable for both low voltage and medium voltage applications, and it can also be used with a variety of accessories for additional flexibility and control. The thermal element is designed to be less sensitive, ensuring that the circuit breaker only trips when necessary.
