Ebony Moulded Case Current Transformers

The Ebony current transformers offers wide system current ratings, apertures, busbar and case sizes to suit every application. Manufactured to meet EN60044 the range benefits include ratio rating from 1/5 to 6000/5, accuracy up to Class 0.5, integral terminal cover for safety and multiple mounting options.

Construction

The toroidal core and secondary winding is encapsulated by a self-extinguishing polycarbonate moulded case cover providing excellent mechanical strength and electrical insulation. The material is halogen free thus reducing risk of halogen emissions in case of fire. The integral covered secondary terminals offer protection to IP20B and the enclosure is protected to IP40.

Interposing Resin Cast Current Transformer

Interposing Resin Cast Current Transformer is manufacture with High quality of raw material is used in the production of our quality gamut. The raw material consists of copper, lamination and stainless steel. These products are ideal to convert the high circuit current to the reduced level. Insulation makes the transformers humidity-resistant, fire-resistant and self-extinguishing. They are available in different specifications, sizes as well as capacities. We present these interposing resin cast current transformers in varied functionalities and specifications as per the requirements of the clients. Used in matching the ratios of main feeder CTs for differential protection schemes. These also find application as saturable CTs used in conjunction with main feeder CTs and thus protect the meters connected to these by limiting the current flowing through the meters.
