The MCT86-60(45) - A9-040052EA110S2 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 service life, and dependable operation in demanding industrial and commercial environments.
Part of the trusted MCT86 series, this model is specifically engineered 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 power control systems. The design allows easy installation without disconnecting the conductor, improving efficiency and minimizing installation time.
The A9-040052EA110S2 variant is optimized for 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 energy meters, ammeters, and protection relays.
Constructed using a high permeability silicon steel core, the CT minimizes energy losses and ensures excellent linearity across varying load conditions. The outer housing is made of flame-retardant thermoplastic, providing superior resistance against heat, dust, and mechanical stress, ensuring durability in harsh operating environments.
Designed in compliance with IS / IEC 61869-2 standards, this current transformer guarantees safety, reliability, and consistent long-term performance. It is widely used by panel manufacturers, OEMs, and electrical engineers in industrial automation, power distribution, and energy management systems.
