Product Description

The Model: Ring Type CT – B3-020055FA110S2 is a precision-engineered Ring Type Current Transformer (CT) designed to deliver accurate current measurement and reliable performance in modern electrical systems. Developed for industrial, commercial, and infrastructure applications, this CT ensures consistent operation, enhanced safety, and long-term durability even in demanding environments.

This current transformer features a solid-core ring design, allowing quick and convenient installation around conductors or busbars without disconnecting the circuit. Its compact and lightweight structure makes it highly suitable for both retrofit installations and new panel assemblies, minimizing installation time and improving operational efficiency.

Manufactured using high-permeability silicon steel core material, the B3-020055FA110S2 provides excellent magnetic performance with minimal hysteresis and eddy current losses. This ensures precise current transformation and stable performance across varying load conditions. The use of high-quality insulation materials enhances dielectric strength, ensuring safe and reliable operation under electrical stress.

The outer casing is constructed from durable, flame-retardant material that offers strong resistance to environmental factors such as dust, moisture, and temperature fluctuations. This robust construction ensures long service life and consistent performance, even in harsh industrial conditions.

Designed for both metering and protection applications, this ring type CT is widely used with energy meters, protective relays, and monitoring systems. It plays a crucial role in accurate load measurement, efficient energy management, and system protection by detecting overloads and abnormal current conditions.
