Blokset Low-Voltage Switchgear
The Blokset cabinet is a branded product of Schneider Electric France. It offers a wide range of cabinet configurations to meet diverse application requirements. The cabinet frame is assembled from standardized prefabricated components, allowing for the creation of switchgear cabinets in various widths and depths through combinations of basic and expansion frames. The switchgear cabinet comprises four distinct compartments: the busbar compartment, the component compartment, the outgoing cable compartment, and the accessory compartment. Feeder units are available in three structural configurations: fixed, plug-in, and drawer-type.
It is suitable for all power generation, distribution, and consumption sites, performing functions such as power collection and distribution at 660 V/220 V, system monitoring and protection, and control and protection of electrical facilities and equipment in the power systems of power plants, substations, industrial and mining enterprises, hotels, ports, and other end-users.
A wide range of cabinet configurations are available to meet the needs of various applications, enabling functions such as power distribution, motor protection, and power factor correction, and are suitable for all low-voltage systems that require high reliability.
D cabinet installation density: 3 MT16 units, 9 NSX630 units, and 24 NSX250 units; U cabinet: 34 motor control circuits.
Ventilation Design for the Top of the Patent Cabinet
The product has successfully passed the 100 kA internal arc fault test, electromagnetic compatibility test, seismic resistance test at intensity 9, and high-altitude test at 5,000 meters, thereby ensuring its safety.
