The MCT140-100H(45) - AB-040056JA110S2 is a high-precision low voltage ring type current transformer designed for industrial metering, monitoring, and protection applications. This model is widely used in electrical distribution systems, switchgear panels, Power Control Centers (PCC), Motor Control Centers (MCC), and energy management systems where accurate current measurement and operational reliability are essential.
Current transformers are important components in electrical systems because they safely convert high primary current into a standard low secondary current suitable for meters, relays, analyzers, and protection devices. The MCT140 series is specially engineered to deliver stable performance, accurate readings, and long operational life under varying electrical load conditions. These CTs are manufactured according to IEC standards for low voltage current measurement applications.
The MCT140-100H(45) - AB-040056JA110S2 features a compact and durable ring type construction that allows easy installation around busbars and insulated conductors. Its flame-retardant polycarbonate enclosure ensures excellent insulation performance, thermal resistance, and mechanical strength, making it suitable for harsh industrial environments. The transformer is designed with finger-safe terminal covers for improved operational safety during installation and maintenance.
This model provides a 400/5A current ratio, converting high primary current into a standardized 5A secondary output for accurate monitoring and energy metering applications. It supports both 50Hz and 60Hz operating frequencies and can be used in low voltage systems up to 720V. The CT also offers excellent thermal and dynamic withstand capability for reliable long-term operation.
The transformer is commonly used in manufacturing industries, commercial buildings, renewable energy projects, industrial automation systems, and infrastructure installations. Electrical contractors, OEM manufacturers, and panel builders prefer this model because of its high accuracy, compact design, and easy mounting facility.
