The MCT86-60(45) - A9-030052CA110S2 Current Transformer (CT) is a high-performance and precision-engineered electrical device designed for accurate current measurement and dependable protection in modern power distribution systems. Built using advanced magnetic core technology and high-quality insulation materials, this CT ensures consistent performance, excellent durability, and long operational life even under demanding industrial conditions.
Part of the robust and widely trusted MCT86 series, this model is specifically designed 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, control panels, and power distribution systems. The design allows easy installation without disconnecting the conductor, improving installation efficiency and reducing downtime.
The A9-030052CA110S2 variant is engineered to provide 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 a wide range of devices such as energy meters, ammeters, and protection relays.
Constructed using a high permeability silicon steel core, this CT minimizes energy losses and ensures excellent linearity across varying load conditions. The outer enclosure is made from flame-retardant thermoplastic, providing strong resistance against heat, dust, and mechanical stress, making it highly suitable for 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 electrical engineers, OEMs, and panel builders in industrial automation, power distribution, and energy management systems.
