Circuit breakers are an essential component of all modern electrical systems. They are designed to cut the power supply to a circuit when the current passing through it exceeds a given level, protecting the circuit from overload and failure. The 279-2-1-51F-9-9M-10-AH circuit breaker is a type of medium-voltage circuit breaker, and is commonly used in a variety of commercial and industrial applications. In this article, we will explore the application fields and working principles of the 279-2-1-51F-9-9M-10-AH circuit breaker.

The 279-2-1-51F-9-9M-10-AH circuit breaker is typically used for medium-voltage applications, ranging from 3.3-44kV. This makes it an ideal choice for commercial and industrial applications that require moderate current and voltage protection. It is also available in a wide range of ratings, from 266A to 6300A, allowing it to be customized for nearly any application. This makes it a versatile and reliable choice for many different types of facilities.

When it comes to the working principles of the 279-2-1-51F-9-9M-10-AH circuit breaker, it operates by internally sensing the current flowing through the circuit. When the current exceeds the pre-set level, it trips the breaker, cutting the power to the circuit. This protects the circuit from further damage due to excessive current or voltage. This is done by using a bimetal strip, which bends when heated, and this triggers the breaker.

The 279-2-1-51F-9-9M-10-AH circuit breaker is a popular choice for many different types of commercial and industrial applications. Some of the most common uses include, but are not limited to, power supplies, HVAC systems, and large industrial motors. The breaker\'s medium-voltage rating makes it an ideal choice for many different types of commercial and industrial applications that require high-current and -voltage protection.

The 279-2-1-51F-9-9M-10-AH circuit breaker is built to last and is reliable. It is UL listed and tested to meet the standards of UL 489 and UL 1077, ensuring that it is one of the most reliable products on the market. It is also designed to be easily installed and maintained, and requires minimal maintenance due to its simple design.

In conclusion, the 279-2-1-51F-9-9M-10-AH circuit breaker is a versatile and reliable choice for commercial and industrial applications. Its medium-voltage rating makes it an ideal choice for applications that require moderate current and voltage protection. It is designed to be simple to install and maintain, and is tested to meet several safety standards. This makes it an ideal choice for a variety of different applications.
