The Ring Type Current Transformer – B5-080054JA110S2 is a compact and high-performance device designed for accurate current measurement and reliable protection in low-voltage electrical systems. Built using advanced magnetic core technology and high-grade insulation materials, this current transformer ensures consistent performance, minimal losses, and long operational life.
This model features a ring type (window type) design, allowing quick and hassle-free installation without disconnecting the primary conductor. The cable or busbar can pass directly through the transformer window, making it ideal for retrofit applications as well as new installations. Its compact size makes it suitable for use in space-limited electrical panels, switchgear systems, 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 analysis, and enhanced system protection.
The B5-080054JA110S2 delivers 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 transformer offers 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 rugged construction reduces maintenance requirements and ensures continuous operation.
This current transformer is widely used in electrical panels, switchgear assemblies, energy monitoring systems, and industrial automation setups, where accurate current measurement and protection are essential.
