♦ Kev Tsim Kho SAS7 Modular Sib NqusCircuit Breakeryog ntawm cov thermal-magnetic tam sim no limitying hom, muaj ib tug compact tsim uas tau ua tiav los ntawm tsis tsuas yog txo tus naj npawb ntawm cov khoom, tab sis kuj cov xov tooj ntawm welded pob qij txha thiab kev sib txuas.

♦ Kev xaiv cov khoom tseem ceeb ua kom muaj kev ntseeg siab thiab ua haujlwm ntev.

♦ Ib yam ntawm qhov no yog qhov kev xaiv nyiaj graphite rau kev sib cuag ruaj khov. MCB muaj qhov yooj yim rau kev khiav lag luam nrog kev mus ncig-dawb toggle mechanism-yog li txawm tias thaum tuav tuav hauv txoj hauj lwm ntawm MCB yog rov mus ncig.

Kev xav txog qhov kub thiab txias

SAS7 Modular Sib NqusCircuit Breakeryog calibrated kom tau raws li qhov yuav tsum tau ntawm IECBSEN60898.2 VB8035 Ref Calibration Temperature. Nyob rau lwm qhov kub, cov nram qab no raing yam yuav tsum tau siv.

Nyob ib sab thermal-magnetic MCBs yuav tsum tsis tu ncua loaded ntawm los yog mus txog lawv cov nominal rated tam sim no thaum mounted nyob rau hauv enclosures. Nws yog ib qho zoo engineering xyaum siv gererous de-rating yam tseem ceeb los yog ua kom txaus huab cua dawb ntawm cov khoom siv. Nyob rau hauv cov xwm txheej no, thiab sib xws nrog lwm cov tuam txhab, peb pom zoo kom muaj 66% kev sib txawv yog siv rau MMCB nominal rated tam sim no uas nws yog npaj los thauj cov MMCB tsis tu ncua (ntau tshaj 1 teev).
