104-PR-0.5A

Circuit breakers are a crucial piece of equipment used to automatically turn off electrical systems in the event of short circuits, overcurrents, and other dangerous conditions. The 104-PR-0.5A circuit breaker is a popular choice due to its compact size and reliable performance. This article will discuss the application fields and working principle of the 104-PR-0.5A circuit breaker.

Application Fields

The 104-PR-0.5A is especially suited for residential and light commercial applications, such as in homes and small businesses. It is also commonly used in industrial control panels and control cabinets. The product has a maximum breaking capacity of 500A at the rated voltage of 440V AC, making it a very reliable choice for many applications.

The 104-PR-0.5A is especially ideal for protection in small motors, pumps, and other similar equipment. It is also used in low-power applications, as the product is designed to shut off automatically when overloads are present. Its fast-responding features also make it well-suited for protecting power supplies and sensitive electronic equipment.

Working Principle

The 104-PR-0.5A is based on a single-pole, thermomagnetic principle for operation. This means that its two automatic functions are thermal and trip current. When an overload or short circuit is detected, the thermal function will quickly react and cause the breaker to interrupt the current. The trip current component senses the current and activates a hydraulic delay-action system to disengage the breaker contact.

The 104-PR-0.5A also has a manual reset switch. When the overcurrent or short circuit is removed, the breaker can be reset from the manual switch. The resetting process is quick, easy, and reliable.

The 104-PR-0.5A is equipped with various features to improve its performance. Its dynamic contact area is large, allowing more current to pass through the contacts. Its contact points are silver-plated, providing superior conductivity, and its bimetallic temperature mounting insulator helps prevent leakage. Furthermore, its splicing gal actin is chrome-plated and stainless steel, which offers improved corrosion resistance and better performance.

In conclusion, 104-PR-0.5A circuit breaker is an ideal choice for many residential and light commercial applications. The product is designed to protect sensitive electronics from potential overloads or short circuits. It operates on a thermomagnetic principle and is equipped with a variety of features to improve its performance. By understanding the application fields and working principle of the 104-PR-0.5A, users can make a better decision when selecting a suitable circuit breaker.
