59784-2 specification is a European-grade specification for high-voltage switches, commonly known as circuit breakers. It defines the application fields and working principle of the switches. In the general sense, it is an important measure for the protection of electrical installations against the effects of extreme events such as short circuits, overloads, or a combination thereof. Furthermore, it also plays an important role in the provision of automation for the control of the circuits.

Given its importance, 59784-2 specification requires that the product functions in accordance with a set of established standards. Primarily, it must meet certain requirements for electrical insulation and it must be of a specific voltage rating in order to be considered compliant. Moreover, it must have a reliable working principle so that it can effectively control and protect a circuit from unwanted or potentially hazardous situations.

In this regard, 59784-2 specification defines two distinct application fields for high-voltage switches. The first is the high-voltage switching circuit breaker, wherein the switch is used to protect a given circuit or apparatus from overheating or any damage caused by an overload or short-circuit. Secondly, the switches are also used to provide automation and control of the power distribution for any given installation.

The working principle of circuit breakers in accordance to the 59784-2 specification is very simple. Basically, the switches can be triggered when a certain amount of current is passed through them. Once the current surpasses a preset threshold, the switch will trip and disconnect the circuit, thus preventing any further current from flowing. Furthermore, once the current has been broken, the switch will stay in the disconnect state until the current is reduced to a safe level, at which time the switch will resume its normal operation.

Given the importance of the 59784-2 specification in ensuring the safety and quality of switches, it is important to select the right accessory for any given installation. The accessories used in the 59784-2 specification include crimpers, applicators, and presses.

Crimpers are used to ensure that electrical connections are securely and accurately made. They are designed to crimp and press electrical wires in order to make a strong connection between two or more electrical components. This will ensure that the connections remain intact even under high-voltage conditions.

Applicators, on the other hand, are designed to assist in the installation of switches. They are usually used to place the contact points of the switches in the correct position. The applicators are designed to be easy to use and require minimal effort from the user. Moreover, they are able to accurately position the contacts of the switches to ensure maximum efficiency.

Finally, presses are used to seal the switches in order to ensure maintenance-free operation. They are capable of applying a specified amount of pressure to the switch contact points in order to attach them securely together. This not only prevents corrosion or other damage caused by vibration or movement, but also ensures that the switches remain in top condition.

In conclusion, the 59784-2 specification is an important standard for high-voltage switches. It defines the application fields and working principles of the switches, as well as defines the required accessories for installation, such as crimpers, applicators, and presses. These accessories are designed to ensure that the switches are able to function correctly and without issue, thus protecting the circuits against potential hazards.
