The MCT86-60(45) - A9-040053EA110S2 Current Transformer (CT) is a high-performance, precision-engineered device designed for accurate current measurement and dependable protection in modern electrical power systems. Built using advanced magnetic core technology and high-quality insulation materials, this CT ensures consistent performance, high accuracy, and long service life in both industrial and commercial environments.
As part of the reliable MCT86 series, this model is specifically developed for busbar mounting applications, featuring a window size of 60 mm x 45 mm. This makes it ideal for medium to high-capacity electrical panels, switchgear assemblies, and power distribution systems. The design allows for easy installation without disconnecting the conductor, improving installation efficiency and reducing system downtime.
The A9-040053EA110S2 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 devices such as energy meters, ammeters, and protection relays.
Constructed using a high permeability silicon steel core, the CT minimizes energy losses and maintains excellent linearity across varying load conditions. The outer enclosure 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 current transformer guarantees safety, reliability, and long-term performance. It is widely used by panel manufacturers, OEMs, and electrical engineers in power distribution, industrial automation, and energy management systems.
