The MCT74-40(45) - A8-080053LA110S2 Ring Type Current Transformer is a high-accuracy and rugged device designed for precise current measurement and protection in electrical distribution systems. Built with advanced magnetic core technology and high-quality insulation, this CT ensures reliable performance, minimal losses, and long service life.
This model features a ring type (window type) design, allowing easy installation without disconnecting the primary conductor. The cable or busbar passes directly through the inner window, making it ideal for retrofit installations as well as new panel setups. Its compact design allows seamless integration into switchgear panels, control panels, and distribution boards.
With a rated primary current of 80A and a secondary current of 5A, this transformer converts high current into a standardized output suitable for measuring devices such as ammeters, energy meters, and protection relays. This enables accurate monitoring, load analysis, and system protection.
The CT offers high accuracy performance (Class 1.0, optional Class 0.5), ensuring stable and 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, the transformer provides excellent thermal stability, high dielectric strength, and durability. 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 long-term performance. Its robust design minimizes maintenance requirements and ensures consistent operation.
This current transformer is widely used in electrical panels, switchgear systems, energy management systems, and industrial automation setups, where accurate current measurement and protection are essential.
