Product Description

The MCT74-40(45) - A8-100052JA110S2 is a high-precision Ring Type Current Transformer (CT) designed for accurate current measurement and dependable protection in modern electrical systems. Built for industrial and commercial applications, this CT ensures consistent performance, long service life, and enhanced system safety.

Featuring a toroidal (ring-type) core design, this current transformer allows easy installation over existing cables or busbars without disconnecting the circuit. This makes it highly suitable for retrofit projects, panel upgrades, and compact switchgear installations where space optimization and minimal downtime are critical.

The MCT74-40(45) CT is engineered to deliver high accuracy in both metering and protection applications. It ensures precise current sensing, which is essential for energy monitoring, load analysis, and system diagnostics. Accurate measurement helps improve energy efficiency, reduce operational losses, and enhance overall power management.

Constructed using high-quality CRGO steel core and durable insulation materials, this transformer is capable of operating reliably in demanding industrial environments. It offers excellent thermal and mechanical strength, ensuring stability even under fluctuating load conditions and electrical stress.

Safety is a key aspect of this current transformer. It provides strong electrical isolation between primary and secondary circuits, protecting connected devices such as meters, relays, and monitoring systems. This isolation helps prevent damage during fault conditions and ensures operator safety.

The robust housing, made from flame-retardant engineering plastic, adds an extra layer of protection against environmental factors such as dust, heat, and minor impacts. Its compact and lightweight construction makes it easy to handle and install, while maintaining high performance standards.

This model is widely used in electrical panels, distribution boards, switchgear assemblies, and industrial automation systems. It is also ideal for energy auditing, smart metering systems, and power monitoring applications where reliability and accuracy are essential.

The MCT74-40(45) - A8-100052JA110S2 is a cost-effective and efficient solution for engineers, contractors, and system integrators looking for a dependable current transformer. Its combination of accuracy, durability, compact design, and easy installation makes it an excellent choice for modern electrical infrastructure.
