Igikorwa cyo kurinda icyuma cyumuzingi kigerwaho nigikoresho cyo kurinda relay. Imashanyarazi yumuriro mwinshi ntabwo ifite ibikoresho byumuvuduko wamashanyarazi muke nko kurekura ubushyuhe, kurekura magneti, kurekura munsi ya voltage, nibindi. Niba hari ikosa kumurongo ucirwa urubanza nigikoresho cyo kurinda relay, hamwe numuzunguruko kumena akora gusa kumena ukurikije amabwiriza yo kurinda relay. Guhindura imizigo no guhagarika ibyuma nabyo ntibisabwa kubaha amategeko mugihe umurongo wagize amakosa kuko badashobora guca ikosa ryubu. Inzitizi zumuzunguruko ni switch ifite ubushobozi bwo kuzimya arc ndende kandi igomba gukoreshwa ifatanije nigikoresho cyo kurinda relay.
Turashobora kurangiza ibi bikurikira:
Guhagarika ibintu - birashobora gufungura gusa no guhuza sisitemu nta-imitwaro ihari, kandi nka sisitemu nyamukuru ya wiring sisitemu igaragara yo gutandukana, muburyo bwo kubungabunga nka sisitemu igaragara. Moderi ikoreshwa cyane: GW9, HGW9, GW4, GW5, nibindi
Guhindura imitwaro - irashobora gufungura no gufunga sisitemu isanzwe yimitwaro isanzwe, ariko ntishobora kumena sisitemu ikosa. Moderi ikoreshwa cyane: FZW32
Inzitizi zumuzingi - Irashobora gufungura no gufunga ibintu bisanzwe byimikorere ya sisitemu, ariko kandi irashobora gufungura no gufunga amakosa hamwe numuyoboro mugufi wa sisitemu. Moderi ikoreshwa cyane: ZW32, ZW20, ZW7, ZW8, LW3, nibindi
