The MCT86-60(45) - A9-020055CA110S2 Current Transformer (CT) is a high-performance, precision-engineered device designed for accurate current measurement and dependable protection in industrial and commercial electrical systems. Built with advanced magnetic core technology and superior insulation materials, this CT ensures consistent accuracy, durability, and long-term reliability even under demanding operating conditions.
Part of the robust and trusted MCT86 series, this model is specifically developed for busbar mounting applications, featuring a window size of 60 mm x 45 mm. This makes it highly suitable for medium to high-capacity electrical panels, switchgear assemblies, and power distribution systems. Its design enables easy installation without disconnecting the conductor, saving both time and effort during installation and maintenance.
The A9-020055CA110S2 variant is engineered to deliver high measurement accuracy with minimal phase displacement, ensuring reliable data for energy billing, monitoring, and protection applications. 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 while maintaining excellent linearity across varying load conditions. The outer enclosure is made of flame-retardant thermoplastic, providing enhanced protection against heat, dust, and mechanical stress, ensuring durability in harsh industrial environments.
This current transformer complies with IS / IEC 61869-2 standards, ensuring safety, performance, and reliability. It is widely used by panel builders, OEMs, and electrical professionals in power distribution, automation, and energy management systems.
