Panels of switchboards of the ShchO-90 series
Purpose and scope
TU U 31.2-32236309-003
The switchboard panels of the SCHO-90 series are intended for the acquisition of electrical distribution panels with a voltage of 0.4 kV, used for receiving and distributing electrical energy, protecting against overloads and short-circuit currents.
Structurally, the ShchO-90 panels are a welded frame product made of sheet metal with electrical apparatus placed inside on the plug-in frame.
Boards are made up of panels and installed in electrical rooms. Service shields made from the front side. The maximum cross-section of the connecting cables should be no more than 185 mm2, and their number should not exceed three.
When ordering panels, please fill out the questionnaire.
