Three-Phase Distribution Panel Specifications
This electrical schematic details the Form 2B IP42-rated power distribution panel (PB-2F-1) operating on a 3Ø4W 380/220VAC-50Hz system. The panel features a main 4P 40A 6kA MCB with Form 2B separation and includes comprehensive metering via a Schneider METSEPM2220 power meter with LCD display, providing voltage, current, power factor, frequency, kW, kWh, kVAr measurements plus THD and 15th harmonic monitoring with RS485 communication.
Key Components:
– Main incoming: 4P 40A C-curve MCB (Schneider A9K24440)
– Metering: 3× current transformers (100/5A, Class 1, 5VA)
– Phase indication: R,Y,B indicator lights with fuses
– Protection: 30× RCBO 1P+N 4.5kA 20A 30mA (Schneider EZ9D34620)
The panel features top and bottom cable entry with a total width of 600mm, depth of 225mm, and height of 950mm. Construction uses electro-galvanized steel sheet with epoxy powder coating (RAL 7035) at minimum 50 microns thickness. The wall-mounted enclosure includes internal wiring using 10mm² flexible cables for main circuits (40A) and 4mm² flexible cables for distribution circuits (20A).
