Circuit breakers are essential components in electrical systems, providing overload and short circuit protection, and they play an important role in electrical safety. PR21-62F-10.0A-XX-V is a type of circuit breaker which has been designed to meet the needs of various applications. In this article, the application field and working principle of PR21-62F-10.0A-XX-V circuit breaker will be explained.

The PR21-62F-10.0A-XX-V circuit breaker is designed for general purpose applications. It is used for the protection of electrical circuits against overload, short circuit and earth fault under both normal and abnormal conditions. It is suitable for branch circuits, lighting systems and motor circuits. It is also used for the protection of power supplies and electrical equipment in domestic, industrial and commercial environments. It is a highly reliable device and can be installed easily with its small modular design.

The working principle of the PR21-62F-10.0A-XX-V circuit breaker is based on two main components: the over-current sensing component and the trip-operating component. The over-current sensing component is composed of a bimetallic strip which will expand when it is heated due to an increasing current passing through it. When the current reaches a pre-determined level, the bimetallic strip will be forced to bend, which will triggerthetrip-operating component, causing it to open the circuit. This will prevent the current from damaging the equipment and circuit components.

In addition to its protection function, the PR21-62F-10.0A-XX-V circuit breaker also has other features such as multiple trip levels for different applications, adjustable trip settings for customised protection and the option to reset or switch off the circuit breaker. It has an operating temperature range of -25°C to 70°C and a rated voltage of 250V~500V. The PR21-62F-10.0A-XX-V circuit breaker is UL and C-UL certified, making it suitable for use in most regions.

In conclusion, the PR21-62F-10.0A-XX-V circuit breaker is an essential component in many electrical systems, providing overload and short circuit protection and ensuring safety. It is suitable for a variety of applications, from branch circuits to power supplies, and it is easy to install due to its small modular design. With its adjustable trip settings and the option to reset or switch it off, it offers great flexibility for different applications.
