Circuit Breakers

Circuit breaker is a kind of essential device in the electric system which is mainly used for the protection of electric appliance and electric circuit from overload, short-circuit and over-current. The PR11-42-2.50A-XX-S circuit breaker is one of the most popular circuit breakers in today\'s market. This circuit breaker provides good protection for low-voltage DC and AC applications, and plays an important role in protecting the electrical system from potential dangers.

Application field

The PR11-42-2.50A-XX-S circuit breaker can be used in various fields, such as power distribution, energy storage system, photovoltaic system, electric equipment and automotive industry. It can be used as the primary protection, which can automatically cut off the power supply when the electric circuit is overloaded or short-circuited. It can also be used as back-up protection for the transmission and distribution of electric power, and can be used for emergency protection when the normal protection fails.

Working Principle

The PR11-42-2.50A-XX-S circuit breaker contains two contacts, which can be opened or closed when an electric current flows through them. When the electric current is over-stressed or short-circuited, the contacts will be open automatically, thus disconnecting the circuit. The mechanism is operated by a bi-metallic strip, which is inserted between the two contacts. When an over-current or short-circuit occurs, the bi-metallic strip will heat up and expand, thus opening the contacts and breaking the circuit.

Advantages

The PR11-42-2.50A-XX-S circuit breaker has many advantages, such as high breaking capacity, reliable performance and high safety. It can provide reliable protection for the electrical system, and can prevent the equipment from damage caused by overload, short-circuit and over-current. It also has a good response time and can quickly cut off the power supply when necessary. Moreover, it is easy to install and maintain and has a long operating life.

Conclusion

The PR11-42-2.50A-XX-S circuit breaker is a reliable and effective protection device for low-voltage DC and AC applications. It can provide excellent protection against overload, short-circuit and over-current. It is easy to install and maintain, and has a long operational life. Therefore, it is a very popular device in the market today.
