Ndi electro-mechanical m'chilengedwe.Chofunikira apa ndikuti:
1. imatha kulumikizidwa mbali iliyonse.
2.Imayenderana ndi IEC 61009-2-1 (main voltage odziyimira pawokha RCBO), Ili ndi kutulutsidwa kwa ma electro-mechanical komwe kumagwira ntchito mosatekeseka ngakhale popanda magetsi operekera kapena magetsi otsika kuposa 50V.
3.Type -A: Imateteza ku mitundu yapadera ya DC yotsalira pulsating yomwe siinasinthidwe.
4.Amapereka chitetezo ku vuto la dziko lapansi / kutayikira panopa, kufupikitsa, kudzaza, ndi ntchito yodzipatula.
5.Amapereka chitetezo chothandizira kuti asagwirizane ndi thupi la munthu Mogwira mtima amateteza zipangizo zamagetsi kuti asawonongeke.
6.Amapereka chitetezo chokwanira ku machitidwe ogawa nyumba ndi malonda.
7.high kuswa mphamvu mpaka 10ka.otetezeka kwambiri.
