Product Description

The Model: Ring Type CT – B3-030053CA110S2 is a high-precision 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 under demanding working conditions.

This current transformer features a solid-core ring design, allowing quick and easy installation around conductors or busbars without disconnecting the circuit. This significantly reduces installation time and improves efficiency, making it suitable for both new installations and retrofit applications in electrical panels and switchgear systems.

Manufactured using high-permeability silicon steel core material, the B3-030053CA110S2 provides excellent magnetic performance with minimal hysteresis and eddy current losses. This ensures accurate current transformation and stable output across a wide range of load conditions. The CT maintains precision in both metering and protection applications, making it an essential component for energy monitoring and system safety.

The transformer is enclosed in a durable, flame-retardant housing that offers strong resistance against environmental factors such as dust, moisture, and temperature fluctuations. This robust design ensures reliable performance and extended service life, even in harsh industrial environments. The high dielectric insulation further enhances electrical safety and operational stability.

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 energy efficiency and ensures system protection by identifying overloads and abnormal current conditions.

The B3-030053CA110S2 is built for continuous operation with minimal maintenance requirements, making it a cost-effective and reliable solution for engineers, contractors, and panel manufacturers.
