Kev Piav Qhia Luv:

Daim Ntawv Thov

CJMM1 series molded case circuit breaker (txij no mus hu ua circuit breaker) siv tau rau AC 50/60HZ fais fab faib network circuit nrog rated insulation voltage ntawm 800V, rated operation voltage ntawm 690V thiab rated operation tam sim no ntawm 10A txog 630A, nws siv los faib fais fab thiab tiv thaiv circuit thiab cov khoom siv fais fab los ntawm kev puas tsuaj vim overload, luv luv circuit, under voltage thiab lwm yam faults, nws kuj siv rau kev pib tsis tshua muaj ntawm lub cev muaj zog nrog rau overload, luv luv circuit thiab under voltage tiv thaiv. Lub circuit breaker no muaj qhov zoo ntawm ntim me me, muaj peev xwm tawg siab, luv luv arcing (lossis noarcing) thiab lwm yam, nws tuaj yeem nruab nrog cov khoom siv xws li lub tswb hu, shunt tso tawm, auxiliary contact thiab lwm yam, nws yog ib yam khoom zoo tagnrho rau tus neeg siv. Lub residual current circuit breaker tuaj yeem ntsia ntsug (ntsug installation) lossis kab rov tav (kab rov tav installation). Cov khoom no ua raws li cov qauv ntawm IEC60947-2 thiab Gb140482.

COV CIRCUIT BREAKERS MOLDED CASE (MCCB)

Cov khoom siv hluav taws xob uas muaj pwm (molded case circuit breakers) yog cov khoom siv tiv thaiv hluav taws xob uas tsim los tiv thaiv lub voj voog hluav taws xob ntawm cov hluav taws xob ntau dhau. Cov hluav taws xob ntau dhau no tuaj yeem tshwm sim vim muaj kev thauj khoom ntau dhau lossis luv luv. Cov khoom siv hluav taws xob uas muaj pwm no tuaj yeem siv tau rau ntau yam voltages thiab frequencies nrog rau qhov txwv qis thiab siab dua ntawm kev hloov kho qhov chaw. Ntxiv nrog rau cov txheej txheem tripping, MCCBs kuj tseem siv tau ua cov keyboards txiav tes thaum muaj xwm txheej ceev lossis kev ua haujlwm txij nkawm. MCCBs tau raug qauv thiab kuaj rau overcurrent, voltage surge, thiab kev tiv thaiv qhov txhaum kom ntseeg tau tias muaj kev nyab xeeb hauv txhua qhov chaw thiab kev siv. Lawv ua haujlwm zoo li lub khawm pib dua rau lub voj voog hluav taws xob kom txiav hluav taws xob thiab txo qhov kev puas tsuaj los ntawm kev thauj khoom ntau dhau, av txhaum, luv luv, lossis thaum tam sim no tshaj qhov txwv tam sim no.

Qauv Khoom
