Product Description

The Model: Ring Type CT – B3-040053EA110S2 is a high-precision Ring Type Current Transformer (CT) designed for accurate current measurement and reliable performance in modern electrical systems. Engineered 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 efficient installation around conductors or busbars without disconnecting the circuit. This significantly reduces installation time and simplifies system integration, making it ideal for both new installations and retrofit applications in electrical panels and switchgear assemblies.

Manufactured using high-permeability silicon steel core material, the B3-040053EA110S2 provides excellent magnetic characteristics with low hysteresis and eddy current losses. This ensures accurate current transformation and stable output across a wide range of load conditions. The CT maintains high precision in both metering and protection applications, making it a vital 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 variations. This robust construction ensures reliable operation and extended service life, even in harsh industrial environments. Its high dielectric insulation enhances electrical safety and protects against voltage stress.

Designed for seamless integration with energy meters, protective relays, and monitoring systems, this ring type CT plays a crucial role in load monitoring, energy management, and fault detection. It helps optimize energy usage and ensures system protection by identifying overload conditions and abnormal current flow.

The B3-040053EA110S2 is built for continuous operation with minimal maintenance requirements. Its durability, efficiency, and consistent performance make it a preferred choice for engineers, contractors, and panel manufacturers.
