PR11-2-15.0A-XX-S circuit breakers are designed for application in low voltage power systems, particularly those where type AC circuit breakers are used in switchboards and distribution boards. These devices are also used in certain industrial applications, such as control and protection of electronic equipment, and occasional overloading. Circuit breakers are commonly used to protect against short circuits, overloads, and faults. The PR11-2-15.0A-XX-S is a particularly useful tool to help protect electrical systems from these conditions.

General Working Principle

The working principle of the PR11-2-15.0A-XX-S circuit breaker is quite simple. When the circuit is complete, there is a small amount of current flowing through the breaker, and this causes a magnetic field to be created in it. When current rises too high, the magnetic field increases, causing a metal armature within the breaker to move. This movement breaks the circuit, thus interrupting the flow of electricity and protecting the system.

Motor or Generator Control

The PR11-2-15.0A-XX-S is particularly useful for motor or generator control applications. In motor control applications, the breaker is used to detect when the motor reaches a certain speed and shuts off the power automatically when the set speed is exceeded. This helps to avoid damage to the motor and protect against unsafe conditions. In generator control applications, the breaker is used to detect when the generator exceeds a certain current limit, and will turn itself off to protect the system.

Overload Protection

Overload protection is one of the primary purposes of the PR11-2-15.0A-XX-S. When the current exceeds the rated limit, the breaker will trip and the circuit will be shut off. This protects the circuit from damage caused by excessive current. It is important to note that the breaker must be correctly sized for the application, as an undersized breaker may not be able to handle the current load.

Short Circuit Protection

Another important function of the PR11-2-15.0A-XX-S is short circuit protection. When a short circuit occurs, the breaker quickly trips to shut off the circuit, thereby protecting it from potential damage. This also helps to prevent fires caused by appliances or other components under excessive current draw.

Conclusion

The PR11-2-15.0A-XX-S is a powerful and effective tool for protecting electrical systems from damage or potentially hazardous conditions. It is designed for a variety of applications, including motor or generator control, overload protection, and short circuit protection. It is important to ensure that the correct size breaker is used for the application, as this is critical to its effectiveness.
