The Ring Type Current Transformer – B3-050055JA110S2 is a precision-engineered electrical component designed for accurate current measurement and dependable protection in industrial and commercial power systems. This transformer is manufactured using advanced magnetic core technology and high-grade insulating materials, ensuring stable performance, low energy loss, and long operational life.
Featuring a compact toroidal or ring-type construction, the B3-050055JA110S2 allows conductors or busbars to pass directly through its center for efficient current sensing. This design enables easy installation without disconnecting the electrical circuit, making it ideal for both new installations and retrofit projects. The transformer is widely used in energy metering, monitoring systems, and protection circuits where precise current measurement is essential.
The primary function of this current transformer is to safely convert high primary current into a lower standardized secondary current, typically 5A or 1A. This allows connected meters, relays, and monitoring devices to measure electrical current safely and accurately. Its excellent accuracy and reliability help improve system protection, energy management, and operational efficiency.
Built with a flame-retardant thermoplastic body, the B3-050055JA110S2 offers superior insulation strength and resistance against heat, moisture, and environmental stress. The robust housing protects the internal magnetic core from mechanical damage while ensuring consistent performance even in demanding industrial conditions. Its compact structure also helps save installation space in electrical panels and switchgear systems.
The advanced magnetic core design minimizes hysteresis and eddy current losses, reducing heat generation and improving overall efficiency. This contributes to longer service life and maintenance-free operation. The transformer performs reliably across a wide range of temperatures and load conditions, making it suitable for continuous operation in critical power systems.
