BOR2 Application Field and Working Principle

The BOR2, or Bi-directional Overcurrent Relay, is an electronic protection device used to detect overcurrent in circuits. It is a commonly used protection device in many industrial safety applications, as it can detect changes in the electrical load and act accordingly to protect the components from potential hazards. The primary function of the BOR2 is to detect any current that is over the rated values and disconnect the power supply from the circuit, which helps to prevent any further damage.

The BOR2 is most commonly used in industrial installations such as solar photovoltaics, motors, generators, and power distribution systems. It is generally an add-on device to existing systems, so it can be used for retrofits as well as new installations. The BOR2 is most commonly used when the current load of a circuit exceeds its rated value; this can cause potentially dangerous overloads and short-circuits, therefore, the BOR2 is deployed to detect excessive electrical loads and disconnect the power supply, reducing the risk of damage and potential hazard.

The working principle of the BOR2 is relatively simple. It consists of two independent detection circuits, which are connected in parallel. When an input current is applied, both circuits detect it, and if the current is over the rated value, both detection circuits will disconnect the power supply from the circuit. This disconnection happens when the current exceeds the safe limit. Therefore, the BOR2 is an ideal device for over-current and overload protection.

In addition to its primary use as an over-current protection device, the BOR2 can also be used for controlling motor starters and other related applications. It can be used as a safety device in the presence of excess currents, as it can detect any sudden changes in the load current and disconnect the power supply from the circuit, which helps to limit the damage caused by potential overloads or short-circuits. It is also a good choice for larger installations, as it can easily detect any abnormalities in the electrical system.

Overall, the BOR2 is an indispensable electronic protection device in many industrial applications. It is an effective device for over-current and overload protection, and can detect any sudden changes in the load current and disconnect the power supply from the circuit. It is also highly reliable and can be used for controlling motor starters and other related applications. It is an ideal device for retrofitting existing circuits, as well as for new installations.
