Isici
I-ETM12 yochungechunge lwe-MCB ihambisana nezinga le-IEC 60898-1.Inesitifiketi se-Semko, CE, CB.
Umthamo wokuphuka we-ETM12 yi-6KA, noma i-4.5KA
Uhlobo lokukhubeka luyi-B, C noma ijika lika-D.
Isilinganiso samanje sithi (1A, 2A, 3A, 4A) 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A.Umsinga okaliwe uhlobene nendawo ehlukene kusetshenziswa isibonelo isigxobo esisodwa esingu-10a kuya ku-16a imvamisa sisetshenziselwa ukukhanyisa, ama-ampere angama-20 kuye ku-33 ngokuvamile asetshenziselwa ikhishi nendawo yokugezela, futhi asetshenziselwa isiphephetha-moya nezinye izinto zolayini.Amanye amakhasimende azokhetha i-2 pole, 40ampere kuya ku-63 ampere njengeswishi eyinhloko esikhundleni se-isolator.
I-voltage yokufaka elinganiselwe: 230V, 240V, 230 / 240V (I-Pole engu-1);400 / 415V (izigxobo ezi-2, izigxobo ezi-3)
Inesigxobo esisodwa (1p), izigxobo eziphindwe kabili (2p), izigxobo ezintathu (3p), nezigxobo ezine, okungamasayizi ama-intshi ama-breaker ayintshi eyodwa.
Kukhona inkomba yesikhundla efakwe emikhiqizweni, Okubomvu kuvuliwe, Okuluhlaza kuvaliwe.
Amatheminali e-MCB ayisivikelo se-IP20 esidizayinelwe ukuthinta iminwe nesandla kuphephile ukuze kugcinwe ukuphepha ngesikhathi sokufakwa.
I-ETM12 MCB ingasebenza ngokuthembekile endaweni enzima, endaweni yokushisa ephakathi -25°C kuya ku-55°C.
Impilo kagesi ingaba imisebenzi efinyelela ku-8000 kanye nempilo yemishini kuze kufike ku-20000, kuyilapho imfuneko ye-IEC ingukusebenza okungu-4000 kanye nokusebenza okungu-10000 kuphela.
Uhlobo lokukhweza luyi-plug-in kutheminali ephezulu, ngezansi kwezintambo.
