The MCT74-40(45) - A8-080052IA110S2 Ring Type Current Transformer is a high-accuracy and durable device designed for precise current measurement and protection in electrical distribution systems. Built with advanced magnetic core technology and superior insulation materials, this current transformer ensures consistent performance, safety, and long operational life.
This model features a ring type (window type) design, allowing easy and quick installation without disconnecting the primary conductor. The cable or busbar can pass directly through the transformer window, making it ideal for retrofit installations as well as new electrical panel setups. Its compact design allows easy integration into switchgear panels, control panels, and distribution boards.
With a rated primary current of 80A and a secondary current of 5A, this CT efficiently converts high current into a standard measurable output suitable for instruments like ammeters, energy meters, and protection relays. This ensures accurate monitoring, load analysis, and system protection.
The transformer provides high accuracy performance (Class 1.0, optional Class 0.5), ensuring reliable readings even under varying load conditions. It is suitable for both metering and protection applications.
Manufactured using a CRGO silicon steel core and epoxy resin cast insulation, this CT offers excellent thermal stability, high dielectric strength, and resistance to environmental conditions. It operates efficiently within a temperature range of -10°C to +55°C, making it suitable for industrial and commercial environments.
The product complies with IEC 61869 and IS 2705 standards, ensuring safety, reliability, and durability. Its rugged construction and low maintenance requirements make it a cost-effective solution for long-term use.
This current transformer is widely used in electrical panels, switchgear systems, energy management systems, and industrial automation setups, where accurate current measurement and system protection are essential.
