The MCT86-60(45) - A9-050056LA110S2 Current Transformer (CT) is a high-performance, precision-engineered device designed for accurate current measurement and reliable protection in modern electrical power distribution systems. Built using advanced magnetic core technology and premium insulation materials, this CT ensures stable performance, high accuracy, and long operational life even 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 × 45 mm. This makes it ideal for medium to high-capacity installations such as switchgear panels, distribution boards, and power control systems. Its design allows easy installation without disconnecting the conductor, improving installation efficiency and reducing system downtime.
The A9-050056LA110S2 variant is engineered to deliver high measurement accuracy with minimal phase displacement, ensuring precise readings for energy monitoring, billing, and protection systems. It converts high primary current into a standardized secondary output (typically 5A or 1A), making it compatible with 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 enclosure is made from flame-retardant thermoplastic, providing superior resistance against heat, dust, and mechanical stress, ensuring durability in harsh industrial environments.
Designed in compliance with IS / IEC 61869-2 standards, this CT guarantees safety, reliability, and consistent long-term performance. It is widely used by panel builders, OEMs, and electrical engineers in power distribution, industrial automation, and energy management systems.
