He aha ngā tohu e tohuhia ana e ngā tawhā i runga i te MCB?

Ngā whati ara iahiko iti (MCB) e whakamahia ana hei tiaki i ngā ara iahiko mai i ngā ara iahiko poto me ngā taumaha rawa, ā, ka taea hoki te whakamahi i roto i ngā pūnaha tohatoha hiko mō ngā rama, mō ngā motuka rānei.
He ātaahua, he kiato hoki tōna āhua, he mama, he pai, he pono hoki tana mahi, he nui te kaha ki te pakaru, he tere te takahi, he ngāwari te tāutanga o ngā ara ārahi, ā, he roa te ora o te mahi.
He maha ngā tohu kei runga i te mīhini pakaru hiko iti (MCB). He aha te tikanga o aua tohu?

1. He aha te tikanga o te kupu “C20”?
Ko te 20 te iahiko whakatauranga, nō reira he aha te tikanga o te kupu C? Ko te C te tohu mō ngā āhuatanga o te takahuri tere o te kaiwawao ara iahiko, e wehea ana ki ngā momo B, C me D;
Momo B (3-5) Ka whakawetohia te hiko In i te 3 ki te 5 ngā wā o te iahiko kua whakatauria. He pai mō ngā kawenga ātete noa me ngā ara iahiko rama iti-aro. He iti te iahiko tīmatanga o tēnei momo kawenga, ā, e whakamahia whānuitia ana i roto i ngā rama kāinga, i ngā wāhi rānei he nui ngā whakaritenga tiaki.
Ko te Momo C (5-10) In ka whakawhāititia i te 5 ki te 10 ngā wā o te iahiko kua whakatauria. He pai mō ngā kawenga whakapūmau me ngā ara iahiko rama tairongo-teitei, pērā i ngā rama halogen tungsten. He nui te uara iahiko o ōna āhuatanga tīmatanga, ā, e whakamahia whānuitia ana i roto i te tiaki ara iahiko tohatoha. me ngā kawenga rama he iahiko āhuatanga tīmatanga teitei.
Ko te Momo D (10-14) In ka whakawhāititia i te 10 ki te 14 ngā wā o te iahiko kua whakatauria. He pai mō ngā pūnaha tohatoha hiko me ngā kawenga whakaawe nui me ngā iahiko pānga nui, pērā i ngā motuka, ngā takirere solenoid me ētahi atu kawenga. He nui ake ngā kawenga pānga o aua kawenga.

Ko te 2.240V/400V 50Hz/60Hz e pā ana ki ngā ara iahiko e tika ana;
3. Ko te IEC60898 e pā ana ki te paerewa hiko hangarau o te ao IEC60898.
4. He aha te tikanga o te 4500A kei raro? He iahiko hiko?
He au tino ia, e pā ana ki te au pakaru mōrahi. Arā, ina puta he ara iahiko poto i runga i te raina, ki te nui ake te au i te 3000A, kāore pea e momotu. He rerekē tēnei tawhā mō ngā kaihanga rerekē.

5. He aha te tikanga o tēnei tohu?
E tohu ana tēnei tohu he rua ngā mahi ārai (tiaki) a te kaiwawao hiko mō te taumaha rawa me te ara iahiko poto.
