Tsim tshiab CJMM3-160L/3300 160A 3P 25kA 415V 690V MCCB Moulded Case Circuit Breaker

Kev Piav Qhia Luv:

CJMM3 Moulded case circuit breaker (txij no mus hu ua circuit breaker) muaj cov yam ntxwv ntawm qhov me me, muaj peev xwm tawg tau zoo, luv luv arc, thiab tiv thaiv kev co. Nws yog qhov tsim nyog rau cov tes hauj lwm faib hluav taws xob nrog AC 50Hz, qhov ntsuas hluav taws xob ua haujlwm 400V, thiab qhov ntsuas hluav taws xob ua haujlwm txog li 250A thiab qis dua. Nws yog siv los faib hluav taws xob thiab tiv thaiv cov kab thiab cov khoom siv hluav taws xob los ntawm kev thauj khoom ntau dhau, luv luv circuit thiab lwm yam kev ua yuam kev. Nws kuj tseem siv tau rau kev hloov pauv tsis tshua muaj hauv cov circuits thiab kev pib tsis tshua muaj ntawm cov motors. Lub circuit breaker tuaj yeem ntsia tau ntsug (uas yog, ntsia ntsug) lossis kab rov tav (uas yog, ntsia kab rov tav).

Cov khoom no ua raws li IEC60947-2 thiab GB/T14048.2 "Cov khoom siv hluav taws xob tsawg thiab cov khoom siv tswj hwm Ntu 2: Cov khoom siv hluav taws xob".
