The MCT86-60(45) - A9-030056IA110S2 Current Transformer (CT) is a high-performance, precision-engineered device designed for accurate current measurement and reliable protection in modern electrical power systems. Manufactured using advanced magnetic core technology and premium insulation materials, this CT delivers consistent accuracy, long-term durability, and dependable performance even in demanding industrial environments.
Part of 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 control systems. Its design allows for easy installation without disconnecting the conductor, improving installation efficiency and reducing system downtime.
The A9-030056IA110S2 variant is engineered to provide high measurement accuracy with minimal phase displacement, ensuring precise readings for energy monitoring, billing, and protection systems. It efficiently converts high primary current into a standardized secondary output (typically 5A or 1A), making it compatible with a wide range of electrical instruments such as energy meters, ammeters, and protection relays.
Constructed with a high permeability silicon steel core, this current transformer minimizes energy losses while maintaining excellent linearity across varying load conditions. The outer housing is made from flame-retardant thermoplastic, providing strong resistance against heat, dust, and mechanical stress, ensuring durability in harsh operating environments.
Designed in compliance with IS / IEC 61869-2 standards, this CT ensures safety, reliability, and consistent performance over a long service life. It is widely used by panel manufacturers, OEMs, and electrical engineers in power distribution, automation systems, and energy management applications.
