ZEMCT303A 40A/40mA Current Transformer

ZEMCT303A Current Transformer is a compact current transformer for isolating and converting high current into a lower current for measurement applications. It supports current measurement, accurate power measurement, overcurrent detection, and protection of relays and measuring equipment. The transformer uses epoxy encapsulation and is designed for precise current and voltage measurement. The output leads are red and black, with the same polarity on P1 and the red wire. It is a straight-through type current transformer with an operating temperature range of -40ºC to +85ºC.
