| * Ucingo lwemagnethi luthathwa njengenxalenye ephilayo engafakwanga.Apho i-voltage ingadluli kwi-375 V, umgama omncinci we-2.4 mm emoyeni okanye kumphezulu uyamkeleka phakathi kocingo lwemagnethi, oluxhaswa ngokuqinileyo kwaye lugcinwe kwindawo kwikhoyili, kunye nenxalenye yentsimbi efileyo.Apho i-voltage ingadluli kwi-750 V, isithuba se-2.4 mm siyamkeleka xa ikhoyili ifakwe ngokufanelekileyo okanye ifakwe. | |||||||||
| Umgama we-creepage phakathi kwezixhobo ezihlawulisiweyo eziqinileyo (ezifana ne-diodes kunye ne-thyristors kwiibhokisi zetsimbi) kunye nesiseko sesinyithi esixhasayo sinokuba sisiqingatha sexabiso elichazwe kwitheyibhile, kodwa ayiyi kuba ngaphantsi kwe-1.6mm. | |||||||||
