The MCT74-40(45) - A8-080056MA110S2 Ring Type Current Transformer is a high-precision and robust device designed for accurate current measurement and reliable protection in electrical distribution systems. Engineered with advanced magnetic core technology and premium insulation materials, this current transformer ensures consistent performance, low energy losses, and long operational life.
This model features a ring type (window type) design, enabling quick and easy installation without disconnecting the primary conductor. The cable or busbar can pass directly through the transformer window, making it highly suitable for retrofit applications as well as new installations. Its compact and durable structure 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 CT efficiently converts high current into a standardized output suitable for measuring instruments such as ammeters, energy meters, and protection relays. This ensures accurate monitoring, load management, and system protection.
The transformer delivers high accuracy performance (Class 1.0, optional Class 0.5), ensuring reliable and stable 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 CT provides excellent thermal stability, high dielectric strength, and resistance to environmental stress. 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, durability, and dependable performance. Its rugged construction minimizes maintenance requirements while ensuring long-term operation.
This current transformer is widely used in electrical panels, switchgear systems, energy monitoring systems, and industrial automation setups, where accurate current measurement and protection are essential.
