The MCT62-30(40) - A5-080055LA110S2 is a high-precision low voltage ring type current transformer designed for accurate current measurement, monitoring, and protection in industrial and commercial electrical systems. This model is widely used in electrical distribution panels, switchgear systems, Motor Control Centers (MCC), Power Control Centers (PCC), and energy management applications where dependable current sensing and operational safety are essential.
Current transformers (CTs) are critical 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 MCT62 series is engineered to provide stable electrical performance, high measurement accuracy, and long operational life under varying load conditions. These CTs are manufactured following international quality standards for industrial metering and monitoring applications.
The MCT62-30(40) - A5-080055LA110S2 features a compact ring type construction that allows easy installation around busbars or insulated conductors in compact electrical panels. Its flame-retardant polycarbonate housing provides excellent insulation strength, thermal stability, and mechanical durability for reliable performance in harsh industrial environments. The transformer also includes finger-safe terminal covers that enhance safety during installation and maintenance procedures.
This model is designed for a 800/5A current ratio, converting high primary current into a standardized 5A secondary output for precise monitoring and metering applications. It supports both 50Hz and 60Hz operating frequencies and is suitable for low voltage systems up to 720V maximum system voltage. The CT offers dependable 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 operation. Its dual terminal connection facility allows easy wiring and convenient shorting during maintenance. Because of its compact design, reliable accuracy, and easy mounting capability, the MCT62-30(40) - A5-080055LA110S2 is widely preferred by panel builders, OEM manufacturers, electrical contractors, and industrial engineers.
