Motor Protection Circuit Breaker J3VE
Nomoro ea sehlahisoa
Likarolo tsa sebopeho
● Letoto lena la li-circuit breakers haholo-holo li entsoe ka mochine, tsamaiso ea ho ikopanya, sesebelisoa sa ho khoptjoa sa arc e timang, setsi sa insulating le shell.
● Li-circuits tsa mofuta oa J3VE1 li na le li-contacts tse thusang.Li-circuits tsa mofuta oa J3VE3 le J3VE4 ha li na li-contacts tse thusang, empa li ka hlomelloa ka lisebelisoa tse thusang tsa ho ikopanya.
● Ho na le mefuta e 'meli ea maeto ka li-circuit breakers: e' ngoe ke bimetallic inverse time delay trip bakeng sa tšireletso e feteletseng;e 'ngoe ke leeto la hang-hang la motlakase bakeng sa tšireletso ea potoloho e khutšoanyane.Mochine oa potoloho o boetse o na le sesebelisoa sa matšeliso a mocheso, kahoo litšobotsi tsa tšireletso ha li amehe ke mocheso o teng.
● J3VE1, J3VE3 le J3VE4 li-circuit breakers li sebelisoa ka konopo, knob le ho sebetsana ka ho latellana.
● Mochine oa potoloho o kenngoa ka pel'a boto.J3VE1, J3VE3, li-circuit breakers li boetse li na le karete e tloaelehileng ea ho kenya, e ka kenngoa ka ho toba seporong se tloaelehileng se nang le bophara ba 35mm (e lokela ho lumellana le DINEN50022).
● Mochini oa li-circuit tsa J3VE3 le J3VE4 o sebelisa mehaho e potlakileng le e potlakileng, 'me lisebelisoa tsa bona tsa ho khoptjoa li na le litšobotsi tse fokolang tsa hona joale, kahoo mochine oa potoloho o na le matla a phahameng a ho senya nako e khutšoanyane.
● Karolo e ka pele ea mochine oa potoloho e na le pointer bakeng sa ho lokisa boemo ba hona joale ba sesebelisoa sa ho khoptjoa, se ka behang lebelo la ho khoptjoa ka har'a moeli o boletsoeng.
● Sekhechana sa potoloho se ka kopanngoa le lisebelisoa tse kang undervoltage release, shunt release, indicator light, lock, le mefuta e sa tšoaneng ea tšireletso ea libaka tse koetsoeng.Ka kopo, hlakisa ha u reka.
