3PLBR6L-024 is a medium voltage air-break switch developed by “TianWei”, a major brand of switchgear in China. It is used for industrial and mining enterprises and other high-voltage switchgear occasions. The rated voltage is 6.3kV, the rated current is 630A and the rated short-time current is 28kA. In order to ensure that the switchgear has reliable insulation and switching performance, special requirements are put forward for the production process, working performance and product structure of the switchgear, so as to ensure the safe operation of the switchgear.

The application field of 3PLBR6L-024 air-break switch includes industrial, mining, electric power, substation, etc. It is mainly used as the high voltage switchgear for load and line breaking, as well as the main switch for controlling external circuit current, overload, shunt or short circuit protection opening. The switchgear should be installed with corresponding power accessories for external circuit current, overload, shunt or incipient short circuit protection, so as to achieve reliable and complete protection for the switchgear.

3PLBR6L-024 air-break switch working principle is mainly based on the mechanical movement of the blade. The mechanical movement of the blade in the air switch can control the opening and closing of the circuit. When the switch is in the off position, the blade is placed in the protection slot, and the air switch is completely in the insulation state. When the switch is in the on position, the blade is in contact with the establishment, and the air switch forms the on state. The air switch reaches the switching effect by controlling the mechanical movement of the blade. It has the characteristics of simple structure and mechanical durability, and is suitable for frequent operation.

In addition, 3PLBR6L-024 air-break switch has the advantages of good safety performance, suitable for safety equipment, and easy installation and maintenance. It is suitable for industrial and mining enterprises, railway locomotives and factories and other high-voltage occasions, to ensure the reliable operation of the switchgear. Therefore, the application of 3PLBR6L-024 air-break switch is very extensive.
