▼Chapter 6Moulded case current transformersApplicationsCurrent transformers are used when currents cannot be directlymeasured. They are a special form of transformers which transformthe primary current into a (mostly) smaller secondary current andgalvanically separate the primary and secondary circuits from eachother. Due to the physically determined saturation aspect of thecore material, additional protection against high currents in thesecondary circuit is achieved.General mechanical propertiesSturdy plastic housing made of polycarbonateFlame resistant in accordance with UL94VOand self extinguishingNickel secondary clamps with positive-negativescrews (2Nm)▼ Integrated secondary clamp platesDimensional drawing IPA40.5All dimensions stated in these drawings are in mm.Dimensional drawing 7A412.3Dimensional drawing 8A512Dimensional drawing 6A315.3Dimensional drawing IPA40165
