The MCT140-100H(45) - AB-050056KA110S2 is a high-accuracy low voltage ring type current transformer specially 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 precise current measurement and operational reliability are essential.
Current transformers (CTs) are important components in electrical power systems because they safely convert high primary current into a lower standardized secondary current suitable for meters, relays, analyzers, and protection devices. The MCT140 series is engineered to deliver stable electrical performance, high measurement accuracy, and long operational life under varying load conditions. These current transformers are manufactured according to IEC standards for low voltage industrial and commercial applications.
The MCT140-100H(45) - AB-050056KA110S2 features a durable ring type construction that enables easy installation around busbars and insulated conductors. Its flame-retardant polycarbonate enclosure provides excellent insulation strength, thermal stability, and mechanical durability, making it suitable for demanding industrial environments. The transformer is equipped with finger-safe terminal covers to improve installation safety and prevent accidental electrical contact.
This model is designed for a 500/5A current ratio, converting high primary current into a standardized 5A secondary output for accurate energy monitoring and metering applications. It supports both 50Hz and 60Hz operating frequencies and can be used in low voltage systems up to 720V maximum system voltage. The CT also provides excellent thermal and dynamic withstand capability for long-term industrial operation.
The transformer is manufactured using high-quality magnetic core material and precision winding technology to ensure low measurement error and stable electrical performance. Its dual terminal connection facility allows convenient wiring and easy shorting during maintenance procedures. Because of its compact design, reliable accuracy, and easy mounting capability, the MCT140-100H(45) - AB-050056KA110S2 is preferred by panel builders, OEM manufacturers, electrical contractors, and industrial engineers for industrial automation systems, commercial buildings, renewable energy installations, and infrastructure projects.
