I-MD-800A isiqophi sekhompyutha semkhumbi, ukulawula nokulawula kwemithombo yomkhumbi kanye nokusebenza, kwenziwe ngokuthi kufanele kwezinkambu ezikhombisiwe, ikhabinethi yezinkambu ezikhombisiwe, ikhabinethi yezinkambu ezincane kanye nokuthuthukiswa kwesistimu noma izinhlobonhlobo ezinye, kungaba yindlela yokusebenzisa kwi-circuit breaker noma i-load switch + i-fuse cabinet. Nokho, kunezinhlelo eziningi zokulawula okuphathelene nokulawula kwemikhumbi yezinkambu, ukulawula kwemikhumbi yezero sequence overcurrent kanye nokusebenza kwezinkambu zokugcina ezithuthukisiwe, kungaba yindlela yokusebenzisa kwi-bus, i-line, i-transformer yezibonelelo, imoto, i-capacitor kanye nokunakekela izinhlelo ezinye.
