Circuit breakers are vital components of any electrical system. They are designed to protect circuits from damage due to overload conditions and short circuits. The 8345-SR0064-125A circuit breaker is a type of miniature circuit breaker (MCB) designed for residential and low-voltage power distribution applications. This article examines the application field and working principle of the 8345-SR0064-125A Miniature Circuit Breaker.

The 8345-SR0064-125A Miniature Circuit Breaker is a highly versatile breaker designed for residential and low voltage power distribution applications. It features a thermal-magnetic trip system which provides maximum protection against short circuits and overloads. Its adjustable trip settings allow the user to tailor the breaker to the specific application. This circuit breaker is also extremely reliable and designed for long lasting operation. Its slim, compact design allows for easy installation and maintenance.

In terms of its application field, the 8345-SR0064-125A Miniature Circuit Breaker is ideal for residential or low voltage applications. It is particularly suitable for light industrial applications, such as small machine fabrication, process line control, and heat treatment. It can also be used for residential power grid protection, such as single family homes, apartment buildings and condominiums. The 8345-SR0064-125A can also be used for motor control applications.

Regarding its working principle, this circuit breaker uses a magnetic-thermal principle which provides maximum protection against short circuits and overloads. When the current level exceeds the set limit, a thermal contact-type switch immediately trips the breaker. The temperature of the contact will then activate a magnetic trip system, which will open the circuit breaker in a fraction of a second. This combination of thermal-magnetic protection ensures the breaker will open quickly and safely in the event of an overload.

The 8345-SR0064-125A Miniature Circuit Breaker also features adjustable trip settings. This allows the user to set the current limit to a range that fits the specific application. The current limit setting can be adjusted easily by using the adjustable screws located on the side panel of the breaker. The trip settings can be modified depending on the level of protection required in a particular application.

In conclusion, the 8345-SR0064-125A Miniature Circuit Breaker is an ideal choice for any residential or low voltage power distribution system. Its thermal-magnetic trip system ensures maximum protection against overloads and short circuits, while its adjustable trip settings allow the user to tailor the protection to the application. This circuit breaker is also extremely reliable and designed for long lasting operation.
