I-electro-mechanical ngokwemvelo.Okugqamayo lapha ukuthi:
1. ingafakwa izintambo kunoma iyiphi indlela.
2.Ihambisana ne-IEC 61009-2-1 (i-RCBO yama-mains voltage ezimele), Ihambisana nokukhululwa kwe-electro-mechanical esebenza ngokuphepha ngisho nangaphandle kwe-voltage yokuhlinzeka noma i-voltage yolayini engaphansi kuka-50V.
3.Uhlobo -A: Ivikela ezinhlotsheni ezikhethekile ze-DC edonsayo eyinsalela engakalungiswa.
4.Inikeza isivikelo ngokumelene nephutha lomhlaba/ukuvuza kwamandla, isiyingi esifushane, ukugcwala ngokweqile, kanye nomsebenzi wokuzihlukanisa.
5.Inikeza isivikelo esihambisanayo ekuthinteni okuqondile ngumzimba womuntu Ivikela ngempumelelo impahla kagesi ekuhlulekeni kokuvikela ukushisa.
6.Ihlinzeka ngokuvikeleka okuphelele ezindleleni zokusabalalisa izindlu kanye nezohwebo.
7.high breaking umthamo kuze 10ka. more evikelekile.
