Lub ntsiab lus txhais ntawm Miniature Residual Current Circuit Breaker

MCB (Miniature Circuit Breaker) yog lub tshuab hluav taws xob me me uas siv rau kev tshaj tawm thiab luv luv - tiv thaiv Circuit Court. RCD (Residual Current Operated Device) yog ib qho khoom siv tiv thaiv uas siv los txheeb xyuas cov dej xau tam sim no thiab txiav tawm hauv Circuit Court. RCBO (Residual Current Operated Circuit Breaker with Overcurrent Protection) yog ib qho kev tiv thaiv hluav taws xob uas ua ke nrog RCD to tiv thaiv thiab MCB overload / luv- tiv thaiv hluav taws xob. Nyob rau hauv sawv cev rau cov ntsuas tam sim no, uas yog qhov siab tshaj plaws tam sim no tus nqi uas lub Circuit Court breaker tuaj yeem nyab xeeb dhau mus ntev. IΔn sawv cev rau qhov ntsuas qhov seem ntawm kev khiav hauj lwm tam sim no, uas yog qhov tsawg kawg nkaus tus nqi tam sim no uas tus tiv thaiv tam sim no ua haujlwm.

 

Qhov no Circuit Court breaker nta me me, lub teeb yuag, siab tawg muaj peev xwm, thiab ceev tripping. Nws siv txoj kev DIN rail mounting txoj kev, thiab nws cov vaj tse thiab cov khoom yog ua los ntawm cov nplaim taws heev -retardant thiab cuam tshuam- yas resistant.

 

DZ ------ Yas Case Circuit Breaker.

 

47 ------ Tsim Code.

 

LE ------ Tshwj xeeb Derivative Code (Electronic Residual Current Circuit Breaker).

 

63 ------ Ncej ntsuas tam sim no (A).

 

Cov "DZ" series yog feem ntau pom nyob rau hauv cov khoom qauv ntawm ib co domestic hom.

 

□ ------ Tus lej ntawm tus ncej.

 

Feem ntau tus ncej naj npawb cim suav nrog: 1P (ib tug ncej, tsuas yog txuas rau theem kab), 2P (ob tug ncej, disconnects ob theem kab thiab kab nruab nrab), 1P + N (ib tug ncej + kab nruab nrab, feem ntau disconnects tsuas yog theem kab, kab nruab nrab tsis yog txiav los yog txiav nyob rau hauv conjunction), 6, siv 3P (3P) peb-wire systems), 4P (plaub ncej, siv nyob rau hauv peb-theem plaub-wire systems).

 

Cov yam ntxwv tripping qhia txog lub Circuit Court breaker cov lus teb ceev rau instantaneous overcurrent (xws li luv luv Circuit Court). Cov hom muaj xws li Hom B (3-}5In, siv rau cov khoom siv hluav taws xob xws li teeb pom kev zoo), Hom C (5-}10In, siv rau kev thauj khoom dav dav thiab me me thiab nruab nrab lub cev muaj zog), Hom D (10-20In, siv rau cov khoom siv hluav taws xob loj xws li transformers thiab compressors), thiab Hom K (siv rau kev tiv thaiv lub cev muaj zog).

 

□ ------ Thaum muaj ib txoj kab nruab nrab uas tsis muaj kev sib txuas, nws tau sawv cev los ntawm N.

 

□ ------ Rated residual operating tam sim no (MA).

 

Raws li qhov loj ntawm cov khoom siv hluav taws xob tam sim no IΔn, cov khoom siv hluav taws xob seem (RCDs) tuaj yeem faib ua: hom rhiab heev (piv txwv li, 6mA, 10mA, siv nyob rau hauv qhov chaw ntub dej xws li chav dej), hom nruab nrab rhiab heev (30mA, feem ntau hauv tsev neeg, siv rau kev tiv thaiv tus kheej hluav taws xob 00), thiab cov hluav taws xob qis tshaj 0. los yog lub ntsiab keyboards).
