Circuit breakers are an integral part of electrical wiring in the modern world. They exist to protect electrical systems when an overload or short circuit is detected in the line. The R11-3-20.0A-20026-2 is a type of circuit breaker used to protect household and office installations from short circuits or overloads.

The R11-3-20.0A-20026-2 is used to protect installations in single- and three-phase houses, commercial buildings, and industrial sites. It is also often used for applications where the circuit breaker needs to be switched on or off in hazardous areas.

The R11-3-20.0A-20026-2 has an adjustable tripping threshold, meaning it can be set to detect faults in the range of 0.2 to 150A. This adjustability makes it suitable for a wide range of applications.

The main feature of the R11-3-20.0A-20026-2 is its fast tripping speed. This means in a short circuit situation, the breaker is able to interrupt the flow of current faster than traditional types. This is essential for protection of sensitive installations, as a fast interruption of the current means the electrical device being protected from damage.

The R11-3-20.0A-20026-2 also has a thermal-magnetic trip unit, meaning that it is able to detect both overloads and short circuits. In the event of an overload, the thermal trip unit will sense an increase in temperature in the internal circuit and the breaker will trip, meaning the circuit is safely disconnected. In the case of a short circuit, the magnetic trip unit will sense an increase in current in the line, and the breaker will trip in order to protect the electrical device being powered.

In order to have optimal protection against both overloads and short circuits, the R11-3-20.0A-20026-2 should be installed in compliance with the national regulations of the region in which it is being used. This means that the tripping times should be configured in accordance with the requirements of the local regulations.

In conclusion, the R11-3-20.0A-20026-2 is an ideal choice for protection against both overloads and short circuits in single- and three-phase houses, commercial buildings, and industrial sites. Its adjustable tripping threshold, fast tripping speed, and thermal-magnetic trip unit make it suitable for a wide range of applications. As with all circuit breakers, it should be installed in compliance with the national regulations of the region in order to provide proper protection against both overloads and short circuits.
