Product Description

The Model: Ring Type CT – B3-025053CA110S2 is a precision-engineered Ring Type Current Transformer (CT) designed to deliver accurate current measurement and dependable performance in modern electrical systems. Developed for industrial, commercial, and infrastructure applications, this CT ensures high accuracy, operational safety, and long-term durability even in demanding environments.

This current transformer features a solid-core ring design, which enables quick and efficient installation around cables or busbars without the need to disconnect the circuit. This not only reduces installation time but also improves system efficiency, making it highly suitable for both new installations and retrofit applications.

Manufactured using high-permeability silicon steel core material, the B3-025053CA110S2 offers excellent magnetic performance with low hysteresis and eddy current losses. This ensures precise current transformation and stable output across varying load conditions. The transformer maintains consistent accuracy, making it ideal for both energy metering and protection applications.

The outer casing is made from high-quality, flame-retardant material that provides excellent resistance against environmental factors such as dust, moisture, and temperature fluctuations. This robust construction ensures reliable operation and extended service life, even in harsh industrial conditions.

Designed for seamless integration with energy meters, protective relays, and monitoring systems, this ring type CT plays a critical role in load monitoring, energy management, and fault detection. It helps improve system efficiency while ensuring safety by detecting overloads and abnormal current conditions.

The B3-025053CA110S2 is built for continuous operation with minimal maintenance requirements, making it a cost-effective and reliable solution for engineers, contractors, and panel manufacturers.
