The MCT86-60(45) - A9-020056FA110S2 Current Transformer (CT) is a high-performance, precision-engineered electrical device designed for accurate current measurement and reliable protection in modern power distribution systems. Built with advanced magnetic core technology and high-quality insulation materials, this CT delivers consistent performance, enhanced safety, and long operational life in demanding industrial and commercial environments.
Belonging to the trusted MCT86 series, this model is specifically designed for busbar mounting applications, featuring a window size of 60 mm x 45 mm. This makes it ideal for medium to high-capacity switchgear panels, distribution boards, and electrical control systems. Its design allows for easy installation without interrupting the conductor, reducing installation time and operational downtime.
The A9-020056FA110S2 variant is engineered to provide high measurement accuracy with minimal phase displacement, ensuring precise readings required for energy monitoring, billing, and protection systems. It efficiently converts high primary current into a standardized secondary current output (typically 5A or 1A), making it compatible with a wide range of electrical instruments such as energy meters, ammeters, and protection relays.
The CT is constructed using a high permeability silicon steel core, which minimizes energy losses while maintaining excellent linearity across varying load conditions. The outer enclosure is made of flame-retardant thermoplastic, offering strong resistance to heat, dust, and mechanical stress, ensuring durability in harsh operating environments.
Designed in compliance with IS / IEC 61869-2 standards, this current transformer ensures safety, reliability, and consistent performance over an extended service life. It is widely used by panel builders, OEMs, and electrical engineers for efficient current measurement in modern electrical systems.
