Cov lus nug nquag

Q1: Qhov txawv ntawm JR28 thiab LRD series yog dab tsi?

A1: Ob leeg yog thermal overload relays los ntawm CDADA. JR28 series txhawb nqa siab dua tam sim no (txog 140A) thiab yog tsim los rau cov contactors loj (txog D150), thaum LRD feem ntau npog qis qis (txog ～104A). Ua haujlwm tau zoo, lawv muaj kev tiv thaiv zoo sib xws - tab sis JR28 tau ua kom zoo rau kev ua haujlwm hnyav.

Q2: Kuv puas tuaj yeem siv JR28 Thermal Overload Relay nrog cov tsis-CDADA contactors?

A2: Txawm hais tias muaj peev xwm ua tau rau qee qhov, kev ua tau zoo thiab kev txhawb nqa yuav tsum tau ua ke nrog CDADA D-series contactors (D9-D150). Mechanical haum, kub dissipation, thiab kev sib koom ua ke nkhaus yog validated raws li ib tug system.

Q3: Yuav ua li cas tiv thaiv theem tsis ua haujlwm hauv JR28?

A3: Yog tias ib theem poob lawm, qhov seem ntawm ob lub conductors nqa tam sim no tsis sib npaug, ua rau cov cua sov asymmetric hauv bimetallic strips. JR28 kuaj pom qhov tsis txaus ntseeg no thiab mus ncig sai dua li qhov qub dhau, tiv thaiv lub cev muaj zog winding puas.

Q4: Puas yog phau ntawv rov pib dua muaj kev nyab xeeb dua li pib pib dua?

A4: Yog - rau cov txheej txheem tseem ceeb. Phau ntawv rov pib dua yuam tus neeg teb xov tooj los tshuaj xyuas thiab tshem tawm qhov txhaum ua ntej rov pib dua. Nws pib rov pib dua yog tsim rau cov khoom siv tsis tu ncua lossis cov chaw taws teeb uas muaj qhov tseem ceeb txuas ntxiv (piv txwv li, cov twj tso kua mis txias).

Q5: Vim li cas thiaj xaiv CDADA JR28 thoob ntiaj teb hom?

A5: CDADA muab:

● Muaj tseeb thermal sib txawv mechanism nrog cov neeg siab

● Kev sib raug zoo nrog D9–D150 contactors—plug-and-play kev ntseeg tau

● Kev sim, nres, rov pib dua, thiab foob ua haujlwm hauv ib chav tsev compact

● Cov nqi sib tw nrog CE-raws li zoo

● Kev txhawb nqa ceev ceev thiab cov ntaub ntawv Askiv rau cov neeg siv khoom thoob ntiaj teb
