Circuit breaker is a switching device for controlling the flow of electricity in an electrical system. It plays the role of protection and control of the electrical system. It can open or close the circuit quickly at any time. PP11-2-20.0A-OA-S is a kind of circuit breaker and has a wide application in the field of electric power and electrical engineering.

The PP11-2-20.0A-OA-S circuit breaker has a rated current of 20A, an instantaneous breaking capacity of 10kA and an operating voltage of AC 400V/660V. It is available in two types. They are mechanical type and thermal type. It can be used in household or commercial applications. It is especially suitable for single-pole circuit breaker and double-pole circuit breaker.

The working principle of PP11-2-20.0A-OA-S circuit breaker is quite simple. When the load current reaches the rated current, the thermal element will be heated and a certain temperature will be reached. At this point, the bimetallic strip will be bent and the circuit breaker will be tripped, thus breaking the circuit and ensuring the safety of the system. If the power supply is disconnected and the temperature is reduced, then the bimetallic strip will be restored to its original shape and the circuit breaker will return to its original state.

In addition, the PP11-2-20.0A-OA-S circuit breaker has a built-in switch for manual on/off operations. This switch can be used to control the flow of current. Moreover, it has an overcurrent and overvoltage protector to prevent damage caused by excessive current or voltage. This makes it an ideal choice for residential and commercial applications.

In conclusion, PP11-2-20.0A-OA-S circuit breaker is a reliable and efficient switching device that can be used in a variety of electrical systems. It can be used to control and protect the system from overcurrent or overvoltage. It is easy to use, cost-effective and can be used in a wide range of applications. It is a good choice for those who need reliable and economical circuit protection.
