Kev Piav Qhia Luv:

Cov ntawv thov

PG-non series breaker yog tsim rau AC 50Hz Los yog 60Hz, 250V/440V circuit nrog overload, luv luv circuit thiab earth leakage tiv thaiv. Thaum muaj kev phom sij ntawm kev poob siab los yog earth leakage, lub switch yuav txiav tawm lub fault circuit tam sim ntawd. Ntxiv mus, qhov rated current ntawm overload tiv thaiv yog adjustable. Tus neeg siv khoom tuaj yeem hloov kho qhov tam sim no raws li qhov xav tau. Yog li nws txoj haujlwm yog zoo heev hauv overload thiab leakage tiv thaiv.
