Product Description

The Model: Ring Type CT – B4-012056AA110S2 is a high-precision Ring Type Current Transformer (CT) engineered to provide accurate current measurement and dependable protection in modern electrical systems. Designed for industrial, commercial, and infrastructure applications, this CT ensures stable operation, enhanced safety, and long-term durability even under demanding working conditions.

This current transformer features a solid-core ring design, enabling quick and convenient installation around conductors or busbars without disconnecting the circuit. This significantly reduces installation time and operational downtime, making it an ideal solution for both new installations and retrofit projects in electrical panels and switchgear systems.

Manufactured using high-permeability silicon steel core material, the B4-012056AA110S2 delivers excellent magnetic performance with minimal hysteresis and eddy current losses. This ensures accurate current transformation and stable output under varying load conditions. The CT maintains high precision for both metering and protection applications, making it a reliable choice for energy monitoring and system safety.

The transformer is enclosed in a durable, flame-retardant housing that offers excellent resistance against environmental factors such as dust, moisture, and temperature fluctuations. This robust construction ensures long service life and dependable performance even in harsh industrial environments. Its high dielectric insulation further 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 critical role in load monitoring, energy management, and fault detection. It helps improve energy efficiency and ensures system protection by identifying overload conditions and abnormal current flow before they can damage electrical equipment.

The B4-012056AA110S2 is built for continuous operation with minimal maintenance requirements, making it a cost-effective and dependable solution for engineers, contractors, OEM manufacturers, and panel builders.
