Abaphukileyo besekethe bahlukaniswe izinhlobo ezintathu: Uhlobo l (uhlobo olujwayelekile), i-Mtype (uhlobo oluphakeme lokuphuka), nohlobo lwe-h (uhlobo oluphakeme (uhlobo oluphakeme) ngokuya ngomkhawulo wawo wokuqhekeka kwesikhashana. Umfutho wesifunda unezici zobukhulu obuncane, umthamo ophakeme we-flashrort fladover, i-anti-vibration, njll. Kungumkhiqizo ofanele womhlaba nemikhumbi.
I-Breaker Breaker ingafakwa ngokuqondile (okungukufakwa okuqondile) noma ngokuvundlile (okungukuthi, ukufakwa okuvundlile).
Umfufula ohlangabezana nezindinganiso: EC60947-2 andGB14048.2
Qaphela: Kunezinhlobo ezine ze-neutral pole (n polefor ezine imikhiqizo
Thayipha i-n-pole ayifaki ngento evulekile yokuqaqa,
Futhi i-n pole ihlala ixhunyiwe, futhi ayivali futhi ivulekile nezinye izigxobo ezintathu;
Uhlobo B N-Pole alufakiwe ngento ebabazekayo ekhona manje,
Futhi i-n pole ihlanganiswe nezinye izigxobo ezintathu; (n pole ahlanganiswe kuqala bese ehlukaniswa);
I-C-Type n Pole ifakwe into edlula manje ebabazekayo,
Futhi i-n pole ihlanganiswe nezinye izigxobo ezintathu; (n pole ahlanganiswe kuqala bese ehlukaniswa):
I-D-Type n Pole ifakwe ngento ekhethekile yokukhishwa, bese i-kepole ihlala ixhunyiwe, futhi ayivali futhi ivulekile nezinye izigxobo ezintathu;
Izimo Zokusebenza Ezijwayelekile
Ukushisa okuphakathi nendawo okuzungezile: Akuphakeme kune-40 ° C (+ 45 * c yemikhiqizo esetshenziswayo esetshenziswayo) hhayi ngaphansi kwe--5 ° C, futhi inani eliphakathi lamahora angama-24 alidluli imikhiqizo evame ukusetshenziswa);
Indawo yokufaka: Ukuphakama akudluli ku-2000m;
Indawo yokufaka: Umswakama ohlobene nomoya awudluli ku-50% lapho izinga lokushisa eliphakeme kakhulu lingu-40 ° CIST lingaba ne-90% ku-20 ° C;
Izinga lokungcola: Izinga 3;
Isigaba sokufaka: Isigaba sokufaka sesifunda esiphambili sekhefu lesifunda kanye nokukhishwa kwe-undervoitage kungu-LL, kanye nesigaba sokufaka yonke eminye imibuthazo ezayo kanye nemibuthano yokulawula yimi;
Umfukha wokujikeleza angamelana nethonya le-airsait airsait sprawld kanye nemisebe yenuzi;
Ukuthambekela okukhulu kokufakwa kwe-circuit breaker ngu- ± 22,5 °;
Umfukha wokujikeleza angasebenza ngokuthembekile ngaphansi kwesimo sokuzamazama komhlaba (4G);
Umfufula wesekethe kufanele ufakwe endaweni lapho kungekho ingozi yokuqhuma, alukho uthuli oluphambukayo, akukho ukugcwala kwensimbi futhi akukho monakalo wokufakelwa;
Umfutho wesifunda kufanele ufakwe endaweni engenayo emvuleni neqhwa.
Ukuhlukaniswa kwabaphuluki besekethe
Thayipha A: Akukho ukukhishwa okungaphezulu okufakiwe ku-NOPE, futhi i-NPOL ihlala ixhunyiwe, futhi ayivali futhi ivulekile nezinye izigxobo ezintathu.
Uhlobo B: Akukho ukukhishwa okungaphezulu kwe-Overcursent kufakwe ku-N Pole, futhi i-N Pole ivaliwe yavulwa kanye nezinye izigxobo ezintathu (i-N Pole ivaliwe kuqala bese ivulwa).
Uhlobo C: I-NO POLE ifakwe ukukhishwa okuphezulu, bese i-Pole ivaliwe futhi ivulwe kanye nezinye izigxobo ezintathu (i-n pole ivaliwe).

Ngokusho kwemodi ye-wiring, ihlukaniswe ngezinhlobo ezine: i-wiring yangaphambili yephaneli, i-wiring yasemuva, i-plug-in Front-panel wiring, kanye ne-plug-in wack-pan-panel.
Ngokusho kohlobo lokukhululwa ngokweqile, kungahlukaniswa ngohlobo lwe-thermal-electromalnetic (oluyinkimbinkimbi) nohlobo lwe-electromagnetic (manjalo).
Ngokusho kokuthi i-Circuit Breaker inezesekeli. Kunezinhlobo ezimbili: ngezesekeli futhi ngaphandle kwezesekeli:
Okunamathiselwe kuhlukaniswe ngezinamathiseli zangaphakathi nokunamathiselwe kwangaphandle;
Izesekeli zangaphakathi zifaka ukukhishwa kwe-shunt, ukukhishwa kwe-undervoltage, othintana naye, kanye nokuxhumana kwe-alamu.Izesekeli zangaphandle zifaka phakathi indlela yokusebenza ejikelezayo, inqubo yokusebenza kagesi, isakhiwo sokusebenzisana kanye ne-terminal block yamadivaysi asizayo, njll.
