1. Circuit Breaker: Wowononga dera ndi gawo lalikulu mu kabati yolamulira, yomwe imagwiritsidwa ntchito kugwirizanitsa kapena kutulutsa mabwalo. Pamene cholakwa monga cholemetsa kapena chozungulira chachifupi chikuchitika, woyendetsa dera amachotsa mwamsanga dera, kuteteza zipangizo zamagetsi ndi machitidwe.
2. Contactor: A contactor ndi chigawo magetsi ntchito kulumikiza kapena kusagwirizana dera. Imagwira ntchito kudzera pamakina a electromagnetic, ndikuyambitsa zolumikizira zake kuti zitsegule ndi kuzimitsa. M'makabati owongolera, zolumikizira zimagwiritsidwa ntchito nthawi zambiri kuwongolera kuyambira ndi kuyimitsidwa kwa zida monga ma mota ndi kuyatsa.
3. Relay: Relay ndi gawo lamagetsi lomwe limagwiritsidwa ntchito kuwongolera mabwalo. Imagwira ntchito kudzera pamakina a electromagnetic, ndikuyambitsa zolumikizira zake kuti zitsegule ndi kuzimitsa. M'makabati owongolera, ma relay nthawi zambiri amagwiritsidwa ntchito kukhazikitsa ntchito monga kuwongolera malingaliro ndi kuwongolera nthawi.
4. Fuse: Fuse ndi gawo lamagetsi lomwe limagwiritsidwa ntchito kuteteza mabwalo ndi zida zamagetsi. Dongosolo likadzaza kapena lalifupi-lozungulira, fusesi yomwe ili mu fuseyi imasungunuka msanga, ndikuchotsa dera ndikuletsa kuwonongeka kwa zida zamagetsi ndi makina.
5. Frequency Converter: Makina osinthira pafupipafupi ndi chipangizo chamagetsi chomwe chimagwiritsidwa ntchito kuwongolera liwiro la mota yamagetsi. Imayendetsa bwino liwiro la injiniyo posintha ma frequency ndi voteji yamagetsi. M'makabati owongolera, ma frequency converter amagwiritsidwa ntchito nthawi zambiri pamapulogalamu omwe amafunikira kuwongolera kuthamanga kwagalimoto, monga kuwongolera mafani ndi mapampu.
