HWK3 uthotho lwezixhobo zolawulo kunye nokhuseleko switsha zisetyenziswa ikakhulu kwisekethe AC 50HZ (60HZ), ulinganiso ombane osebenzayo ukuya 690V. Ilinganiswe ngokusebenzayo ngoku i-1A ukuya kwi-125A, amandla e-motor 0.12KW ukuya kwi-55KW, ngokukodwa isetyenziselwa ukulawulwa kwe-on-off yesekethe, kunye nokukhuselwa kwempazamo yomthwalo womgca. Yamkela imodyuli edibeneyo yesakhiwo, edibanisa imisebenzi ephambili yabaphuli beesekethe, abafowunelwa, i-overload relays, abaqalisi, abahluli kunye nezinye iimveliso. Imveliso enye inokubuyisela indibaniselwano yantlandlolo yamacandelo amaninzi.
