Application
KRON enclosures are used to complete switchgear and main switchboards. They are used to assemble cabinets of control stations, power boxes and other technological units. They are mounted at large enterprises: metallurgical, machine building and shipbuilding plants, agricultural farms: poultry farms and pig breeding complexes. Besides, such modules are suitable for equipping multi-apartment residential buildings, sports stadiums, large fitness centers, retail premises and office organizations. Enclosure reliability guarantees safe and efficient transmission of electric power over the entire chain of connected elements.
Assembly options
KRON is made of high-strength sheet steel. The parts are first laser-cut, and then welded together into a solid frame. The module can be assembled with or without a door. It will have an IP30 or IP55 protection degree, respectively. The enclosure can withstand shock loads and operate in electric current circuits with various voltages up to 4000 A. The structures may differ in dimensions and are allowed for operation in rooms with the ambient temperature from +1 to +40 degrees Celsius. If desired, the internal equipment can be installed on a horizontal surface. For the convenience of transportation to the installation place, the enclosure is provided with special fasteners.
