The MCT86-60(45) - A9-050053FA110S2 Current Transformer (CT) is a high-performance, precision-engineered device designed for accurate current measurement and dependable protection in modern electrical power distribution systems. Manufactured using advanced magnetic core technology and premium insulation materials, this CT ensures consistent accuracy, long-term reliability, and superior performance in demanding industrial and commercial environments.
As 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 installations in switchgear panels, distribution boards, and power control systems. The design allows easy installation without disconnecting the conductor, reducing downtime and improving operational efficiency.
The A9-050053FA110S2 variant is designed 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 using a high permeability silicon steel core, this current transformer minimizes energy losses and maintains excellent linearity across varying load conditions. The outer housing is made from flame-retardant thermoplastic, offering 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.
