Core Zoo
Plaub lub ntsiab lus txiav txim siab seb 250 A nruab nrab taw tes haum rau lub txee koj twb tau tsim.
Dimensioned Rau 250 A Band
Rated 250 A tas mus li ntawm 16-50 mm² ntau yam, qhov no yog lub cev ua rau nruab nrab ntawm qhov ntau, tsis yog 400 A thav duab nrog ib daim ntawv me me - yog li qhov nruab nrab ntawm qhov chaw nres tsheb loj.
Lub cev Compact, txiav txim los ntawm qhov hnyav
Daim duab ntim cov ntawv luam tawm yog tus neeg ncaj ncees: 30 daim rau ib lub thawv 3.2 kg, kwv yees li 100 g ib chav tsev - lub teeb kho vajtse hauv chav kawm no, qhov hnyav dua rau mount thiab nkoj.
Tus nqi Torque rau Kev Qhia Ua Haujlwm
2.0–2.5 N·m ntawm M6 screws yog ib daim duab ntawm lub khw vaj huam sib luag tuaj yeem sau rau hauv cov lus qhia sib dhos thiab kev tshuaj xyuas hauv pem teb - ib qho xoob sib koom ua ke yog vim li cas ib txwm ua haujlwm nruab nrab.
Tin qhov twg Lub Joint Kaw
Tin plating ua rau lub ntsej muag ntawm tooj liab los ntawm oxidising nyob rau hauv cov av noo los yog corrosive nroj tsuag huab cua, yog li qhov sib koom ua ke tsis tuaj yeem sov dua xyoo rau xyoo.
Hlau Cage Terminal vs Traditional Brass Terminal
Cov ntsiab lus los ntawm cov qauv siv; qhov no yog cov ntsia hlau-clamped tooj liab thaiv, yog li lub rooj sib piv nws nrog cov tsoos tooj dag nruab nrab strip. Saib daim ntawv tsim khoom 6.

| Hlau ntau | 16-50 mm², khoom lossis stranded tooj liab | Tsau qhov sib nrug, adapters xav tau |
| Cov ntsiab lus txuas | Ob peb lub ntsiab lus nruab nrab ntawm ib qho - ncej puab | Ib tug conductor rau stud |
Cov txheej txheem kev tshaj lij
Cov txheej txheem khiav hauv 6 qhov haujlwm, thiab txhua tus kaw nrog tus lej sau cia.
Copper block stock raug kuaj xyuas qib ntawm daim ntawv txais nyiaj.
Txhua qhov thaiv yog machined rau daim duab, thiab lub ntsej muag machined yog ntsuas.
Lub PA66 puag yog molded thiab tshuaj xyuas rau flash thiab dimensional drift.
Blocks nkag mus rau hauv lub tin da dej raws li ib tug batch, nrog txheej thickness sampled.
Cov ntsia hlau tau sib sau ua ke, thiab txhua qhov txuas txuas tau raug pov thawj.
Cov chav nyob dhau qhov ntsuas hluav taws xob, tshuab thiab corrosion ua ntej ntim.
Khoom siv & Nto kho kev xaiv
Ob qhov kev txiav txim siab ntawm cov khoom tsim nyog yuav tsum tau daws ua ntej siv, vim tias ob qho tib si nyuaj rau hloov tom qab.
Iav -Txhim kho PA66 Base
Lub rwb thaiv tsev muaj lub zog dielectric siab tshaj 20 kV / mm thiab rwb thaiv tsev tiv thaiv tshaj 100 MΩ ntawm 500 V DC, tuav cov khoom siv hluav taws xob ntshiab ntawm qhov chaw mounting.
Electrolytic Copper Blocks, Tin Plated
High-purity electrolytic tooj liab ua kom qhov sib koom ua ke txias, thiab cov phaj tin tiv thaiv lub ntsej muag uas oxidation yuav txwv tsis pub ua kom muaj kev tiv thaiv txhua xyoo.
Daim ntawv thov Scenario
Peb hom txee qhov twg 250 A nruab nrab taw tes txiav txim qhov layout.
Commercial Distribution Boards Thiab Panelboards
Peb-theem plaub-cov hlau boards hauv cov tsev lag luam, qhov twg ob peb tus neeg ua haujlwm nruab nrab tawm hauv ib lub cev me me es tsis txhob ua cov kab sib cais.
Motor Control Centers Thiab Industrial Control Panels
Tswj vaj huam sib luag pub cov khoom sib xyaw ua ke, qhov chaw sib haum xeeb thiab tsis sib npaug ntawm ib qho -theem circuits thawb nruab nrab tam sim no hauv cov kab no.
PV AC Combiners Thiab Me Me Txee Txee
AC cov khoom sib txuas thiab cov txee me me ntawm lub ru tsev thiab tom qab -- qhov chaw 'meter', qhov chaw nruab nrab yuav tsum tau ntsuas ntau dua li qhov kev tsim kho.
Cov lus nug nquag
Q: Qhov ntsuas 250 A yog dab tsi?
A: Nws ntsuas tus tib - ncej lub cev ntawm 16–50 mm² tooj liab conductor. Tsis muaj ib puag ncig lossis kev teeb tsa hauv paus tau tshaj tawm, thiab txhua qhov taw qhia tsuas yog qhov nws tus kheej tus neeg xyuas pib tso cai rau - xa cov ceg thauj khoom thiab peb lees paub qhov haum.
