Overview
Application
ЩО 90 panels receive and distribute three-phase AC electrical energy at 0,4 kV and 50 Hz, protecting outgoing circuits against overloads and short-circuit currents.
Features
Construction and application
ЩО 90 panels are used in 0,4 kV distribution equipment (РП-0,4 kV) at 220/380 V three-phase AC in networks with an isolated or solidly earthed neutral. Switchboards are assembled from ЩО 90 panels and serviced from the front.
Panel types include incoming, feeder, bus-section and other panels. They have a welded structure of folded sheet profiles containing switching and protective devices and electrical measuring instruments.
Climatic version У3 under ГОСТ 15150-69. Protection under ГОСТ 14254-96 follows the first digit of the circuit number: 1 — open version 1Р00, with 1Р20 at the front; 2 — enclosed version 1Р20, with 1Р00 at the bottom.
ЩО 90 panels comply with ТУ У 31681625.0032004.
