Rated ua hauj lwm voltage (Ue): Qhov no yog qhov voltage uas lub Circuit Court breaker ua hauj lwm nyob rau hauv ib txwm (tsis muaj kev cuam tshuam).
2. Rated tam sim no (Nyob rau hauv): Qhov siab tshaj plaws tam sim no tus nqi uas lub Circuit Court breaker nruab nrog ib tug tshwj xeeb overcurrent mus txawv tebchaws relay muaj peev xwm tiv taus infinitely nyob rau hauv lub ambient kub teev los ntawm cov chaw tsim tshuaj paus, thiab yuav tsis pub tshaj qhov kub txwv teev los ntawm tam sim no bearing tivthaiv.
3. Short-circuit relay trip tam sim no tus nqi (Im): Lub luv luv-circuit mus ncig teb chaws relay (instantaneous los yog luv-delay) yog siv los sai sai mus rau lub Circuit Court breaker thaum muaj ib tug siab txhaum tam sim no tus nqi tshwm sim, thiab nws mus txawv tebchaws txwv yog Im.
4. Rated luv luv-circuit breaking muaj peev xwm (Icu los yog Icn): Qhov ntsuas luv luv-circuit breaker tam sim no ntawm Circuit Court breaker yog qhov siab tshaj (kwv yees) tam sim no tus nqi uas lub Circuit Court breaker tuaj yeem tawg yam tsis muaj kev puas tsuaj. Cov txiaj ntsig tam sim no tau muab rau hauv tus qauv yog tus nqi rms ntawm AC tivthaiv ntawm qhov txhaum tam sim no, thiab DC ntu ntu ntu (uas ib txwm tshwm sim hauv qhov phem tshaj plaws luv luv-circuit) yog suav tias yog xoom thaum xam tus nqi tus qauv. Kev ntsuas hluav taws xob hluav taws xob muaj hluav taws xob (Icu) thiab kev ntsuas hluav taws xob hauv tsev (Icn) feem ntau yog muab rau hauv kA rms.
5. Short-circuit breaking peev (Ics): Lub peev xwm tawg ntawm lub Circuit Court breaker tau muab faib ua ob hom: ntsuas qhov kawg ntawm lub caij luv luv tawg lub peev xwm thiab ntsuas kev ua haujlwm luv-circuit tawg peev xwm.
