4435.0571

Circuit breakers can be defined as a device designed to rapidly open and close off an electrical circuit in order to protect the circuit and its components from damage due to an overload or other hazardous electrical conditions. Among the many types and designs of circuit breakers available today, one of the more common and reliable designs is the 4435.0071. In this article, we’ll take a look at the 4435.0071 application field, working principle and its construction.

4435.0071 Application Field

The 4435.0071 circuit breaker can be used in a variety of applications, including but not limited to: electrical distribution networks, high-current industrial processes, automated machinery, motor circuits, and other applications where reliable, robust and comprehensive overload protection is required. This type of circuit breaker is also UL-recognized, meaning it has been tested for safety and performance by an independent third party.

Working Principle

The 4435.0071 circuit breaker works on the concept of electromagnetism. When the current flowing through the breaker exceeds its rated limit, a large electromagnet (bimetal) is activated, and this causes the breaker’s contacts to open. This action trips the breaker, thereby protecting the circuit from any further electrical overloads. This type of circuit breaker does not require a manual reset, as it is self-resetting.

Construction

The 4435.0071 circuit breaker consists of two main parts, the body and the backplate, along with other components. The body is made of steel or aluminum and holds all the components, while the backplate consists of an insulated insulation and contains the motion detector and contacts. Inside the breaker, a light and motion detection system is used to detect overcurrents. This system consists of a light source, a lens, and a photocell. When an overcurrent is detected, the photocell sends a signal to the breaker, which in turn activates the electromagnet that opens the contacts. The contacts then remain opened until either a manual reset is applied or the current drops to a safe level.

In conclusion, the 4435.0071 circuit breaker is a reliable and robust solution for applications where overload protection is critical. With its self-resetting operation and UL-recognized construction, the 4435 is an ideal circuit breaker for a variety of applications.
