DZ47LE-63 RCBO idapangidwa kuti iteteze magetsi otsika mphamvu. Ngati magetsi atatuluka kapena kukhudzana ndi anthu mwangozi, imatha kutseka magetsi mwachangu mkati mwa masekondi 0.1, ndikuletsa ngozi zamagetsi komanso moto wamagetsi. Ndi yoyenera makina ogawa magetsi m'nyumba ndi m'mafakitale, imapereka chitetezo chokwanira ku kutayikira, kudzaza kwambiri, komanso zolakwika zafupikitsa nthawi.

Chipangizo choteteza ma surge cha RDSP6 series, chimagwiritsidwa ntchito makamaka pa TN-C, TN-S, TT, IT power system ya AC50Hz kapena 60Hz, nominal discharge current 5KA~60kA, Maximum discharge current 10KA~100KA. Voltage yogwira ntchito yoyesedwa ndi 220V kapena 380V.

Imateteza ma gridi amagetsi ku magetsi ochulukirapo omwe amayambitsidwa ndi mphezi komanso magetsi ochulukirapo omwe amatuluka, ndikuletsa zotsatira zoyipa kudzera mu mphamvu yake yoyankha mwachangu kwambiri. Chifukwa cha makhalidwe amenewa, imagwiritsidwa ntchito kwambiri m'nyumba, mayendedwe, magetsi, mafakitale achitatu komanso m'mafakitale okhudzana ndi chitetezo cha magetsi.

RDJ2 (LR2) series bimetal type thermal over-load relay ndi yoyenera pa dera la AC 50Hz/60Hz rated operating voltage Ue:660V, rated current 0.10~630 (A), monga kugwiritsa ntchito over-load, break gation ndi chitetezo cha mota ndi dera.

Kutumiza kwa kutentha komwe kumakhudza ntchito ndi mawonekedwe a chitetezo cha gawo losweka, kusintha kwa current, kusankha kosankha kokonzanso zokha ndi kubwezeretsa pamanja, chizindikiro chosonyeza zochita, kulekanitsa kutentha kwa NO, ma contact othandizira a NC, gawo laling'ono loyika, ndi njira zosiyanasiyana zoyikira.

Komanso, ili ndi mabatani oyesera ndi oimitsa. Ndipo imatha kuyang'aniridwa kusinthasintha kwa zochita, ili ndi chivundikiro choteteza chomwe chimaletsa dzanja kuti lisagwedezeke, chotetezeka kugwiritsa ntchito, ndilChipangizo chokhoma kuti chisagwire ntchito molakwika ndi zina zotero. Chogulitsachi chikutsatira: miyezo ya IEC60947-4-1.

CJX2 series AC contactor idapangidwa kuti igwiritsidwe ntchito m'mabwalo a AC okhala ndi ma frequency a 50Hz kapena 60Hz, yokhala ndi voteji yogwira ntchito yofika 690V komanso voteji yogwira ntchito yofika 780A.

Ntchito yake yayikulu ndikulola kuti kulumikizana kwa dera kukhale kotetezeka komanso kosavuta, zomwe zimathandiza kuti magetsi azigwira ntchito bwino komanso mosavuta. Kuphatikiza apo, contactor imatha kuphatikizidwa ndi thermal relay kuti ipange choyambira chamagetsi, chomwe chimapereka chitetezo chodalirika cha overload pa dera lolumikizidwa.

Chogulitsachi chikugwirizana kwathunthu ndi muyezo wapadziko lonse wa IEC/EN 60947-4-1, kuonetsetsa kuti chikutsatira miyezo yachitetezo cha makampani padziko lonse lapansi komanso magwiridwe antchito.

PDL-100 RCCB idapangidwa kuti ikhale yodalirika: yolondola kwambiri, yokhala ndi zinthu zochepa komanso yopanda mphamvu yothandizira. Yopangidwira makina a AC 50/60Hz, imathandizira ma circuits a 230V amodzi ndi magawo atatu a 400V (ndi pansi pake). Ntchito yake yayikulu ndikuletsa moto wamagetsi ndi ngozi zaumwini zomwe zimachitika chifukwa cha magetsi a anthu kapena kutuluka kwa gridi, imagwira ntchito ngati chipangizo choteteza chomwe chimagwira ntchito mwachangu, chogwiritsa ntchito maginito okha, komanso chogwiritsa ntchito magetsi.

Chojambulira cha chinthucho chimagwiritsidwa ntchito kuyesa kusiyana kwa vekitala kwa mphamvu yodutsa, ndipo chimapanga mphamvu yotulutsa yoyenera ndikuyiwonjezera ku tripper mu secondary winding, ngati mphamvu ya vekitala ya vekitala yotetezedwa ya kugwedezeka kwamagetsi kwa munthu ili pamwamba kapena pamwamba pa mphamvu yogwira ntchito, tripper idzachitapo kanthu ndikudula kuti chinthucho chigwire ntchito ngati chitetezo.

Chotsekera ma circuit cha RDB5-63 chapangidwa kuti chigwiritsidwe ntchito pa ma circuit omwe amagwira ntchito pa AC50/60Hz, 230V/240V(1P), 400/415V(2,3,4P), chomwe chimapereka chitetezo chodalirika cha overload ndi short circuit ndipo chimagwira ntchito ngati switch ya mzere wosinthira womwe suchitika kawirikawiri. Cholinga chake chachikulu ndi kukhazikitsa magetsi m'nyumba komanso kukhala choyenera makina ogawa magetsi amalonda ndi mafakitale.

Ma RDM5 a Moulde Case Circuit Breakers (MCCB) amagwiritsidwa ntchito makamaka m'malo ogawa magetsi omwe amagwira ntchito pa AC 50Hz, okhala ndi voteji yoteteza ya 1000V, voteji yogwira ntchito ya 690V kapena yotsika, komanso mphamvu yamagetsi yofikira 800A. Zipangizozi zimathandiza kugawa mphamvu zamagetsi pamene zikuteteza mizere yamagetsi ndi zida kuti zisachuluke kwambiri, komanso kuwonongeka komwe kumachitika chifukwa cha zolakwika monga ma short circuits ndi mikhalidwe ya voteji.

Chochititsa chidwi n'chakuti, ma breaker okhala ndi mphamvu yamagetsi ya 630A kapena kuchepera ndi oyeneranso kugwiritsa ntchito poteteza injini. Munthawi yogwira ntchito bwino, ma circuit breaker awa angagwiritsidwe ntchito posintha ma circuit pafupipafupi komanso poyambitsa injini nthawi zina.
