Uhambo lweMagnetic olushushu

Ukutshiza ngemagnethi obushushu yindlela yendabuko edibanisa iindlela ezimbini ezahlukeneyo: ubushushu kunye nemagnethi. I-thermal element isebenza ngomgaqo wobushushu obuveliswa kukuhamba komsinga wombane. Xa umsinga udlula umda omiselweyo, umcu we-bimetallic uyatshisa kwaye ugobe, ekugqibeleni ubangele indlela yokutshiza. Le nkqubo icotha kakhulu kwaye ivumela ukugqithiswa kwexeshana ukuba kudlule ngaphandle kokuphazanyiswa, okuluncedo kwizicelo ezihlala zifumana imisinga yokungena, njengeemoto.

Kwelinye icala, icandelo lemagnethi lisabela kwiisekethe ezimfutshane. Lisebenzisa ikhoyili ye-electromagnetic edala intsimi yemagnethi xa umsinga omkhulu udlula kuyo. Le ntsimi yemagnethi itsala i-lever, ikhube i-circuit breaker phantse ngoko nangoko, inika ukhuseleko olukhawulezileyo lwesekethe emfutshane. Ukudibana kwezi ndlela zimbini kwenza i-MCCB ye-thermal-magnetic ibonelele ngokhuseleko oluthembekileyo lwe-overload kunye ne-short circuit.

Uhambo lwe-elektroniki
