Cov parameters ntawm MCB sawv cev rau dab tsi?

Cov khoom siv hluav taws xob me me (MCB) feem ntau yog siv los tiv thaiv cov circuits los ntawm luv luv circuits thiab overloads, thiab kuj tseem siv tau rau hauv cov kab ke faib hluav taws xob rau teeb pom kev zoo lossis motors.
Nws yog tus cwj pwm zoo nkauj thiab me me, lub teeb yuag, kev ua tau zoo heev thiab txhim khu kev qha, muaj peev xwm tawg siab, tripping sai, yooj yim installation ntawm cov kev taw qhia thiab lub neej ntev.
Muaj ntau lub cim ntawm lub tshuab hluav taws xob me me (MCB). Lawv txhais li cas?

1. "C20" txhais li cas?
20 yog qhov ntsuas tam sim no, yog li C txhais li cas? C sawv cev rau cov yam ntxwv ntawm lub tshuab hluav taws xob tam sim ntawd, uas muab faib ua B, C thiab D hom;
Hom B (3-5) Hauv yog tripped ntawm 3 txog 5 zaug ntawm qhov tam sim no ntsuas. Nws yog tsim rau cov khoom siv resistive thiab cov teeb pom kev zoo tsis tshua muaj zog. Hom khoom no muaj qhov pib me me tam sim no thiab feem ntau yog siv rau hauv tsev teeb pom kev zoo lossis qhov chaw uas muaj kev tiv thaiv siab.
Hom C (5-10) Hauv yog tripped ntawm 5 txog 10 npaug ntawm qhov tam sim no ntsuas. Nws yog qhov tsim nyog rau cov khoom siv inductive thiab cov teeb pom kev zoo siab, xws li cov teeb tungsten halogen. Nws cov yam ntxwv pib muaj tus nqi tam sim no siab thiab feem ntau yog siv rau hauv kev tiv thaiv Circuit Court faib khoom. thiab cov teeb pom kev zoo nrog cov yam ntxwv pib siab.
Hom D (10-14) Hauv yog tripped ntawm 10 txog 14 npaug ntawm qhov tam sim no ntsuas. Nws yog qhov tsim nyog rau cov kab ke faib hluav taws xob nrog cov khoom siv inductance siab thiab cov khoom siv cuam tshuam loj, xws li lub cev muaj zog, solenoid valves thiab lwm yam khoom thauj. Cov khoom thauj no muaj cov khoom thauj cuam tshuam siab dua.

2.240V/400V 50Hz/60Hz yog hais txog cov circuits uas siv tau;
3.IEC60898 yog hais txog tus qauv hluav taws xob thoob ntiaj teb IEC60898.
4. Lub 4500A nyob hauv qab txhais li cas? Puas yog hluav taws xob tam sim no?
Nws yog qhov tseeb tam sim no, uas yog hais txog qhov siab tshaj plaws tam sim no tawg. Ntawd yog, thaum muaj luv luv tshwm sim ntawm kab, yog tias tam sim no loj dua 3000A, nws yuav tsis raug txiav. Qhov parameter no txawv rau cov chaw tsim khoom sib txawv.

5. Lub cim no txhais li cas?
Lub cim no qhia tau tias lub circuit breaker muaj ob txoj haujlwm tripping (kev tiv thaiv) rau kev overload thiab luv circuit.
