Chozungulira chapa kutulutsidwa kwaposachedwandipo chinthu chotenthetsera cha kutulutsidwa kwa kutentha chimalumikizidwa motsatizana ndi dera lalikulu, ndi chozungulira chakutulutsidwa kwa undervoltageimalumikizidwa limodzi ndi magetsi.
Pamene dera lafupikitsidwa kapena lodzaza kwambiri, armature yakutulutsidwa kwamphamvu kwambiriadzakoka kuti agwire ntchito mopanda kugwedezeka, ndipo cholumikizira chachikulu chidzachotsa dera lalikulu.
Pamene dera ladzaza kwambiri, chinthu chotenthetsera cha thermal tripper chidzapinda pepala la bimetal, kukankhira njira yochepetsera kuti igwire ntchito, ndipo cholumikizira chachikulu chidzachotsa dera lalikulu.
Pamene dera lilimphamvu yamagetsi yopanda mphamvu, chida chakutulutsidwa kwa undervoltageimatulutsidwa, zomwe zimapangitsanso kuti njira yolumikizirana ndi ma free tripping igwire ntchito, ndipo kukhudzana kwakukulu kumachotsa dera lalikulu.
Pamene batani lotulutsa shunt lakanikiza, armature yakutulutsidwa kwa shuntchimakokedwa, zomwe zimapangitsa kuti njira yopunthira yaulere igwire ntchito, ndipo kukhudzana kwakukulu kumachotsa dera lalikulu
