Current Transformer- ZMCT118F 30A
(Ask For A Quotation)A current transformer (CT) is used for measurement of alternating electric currents. When current in a circuit is too high to apply directly to measuring instruments, a current transformer produces a reduced current accurately proportional to the current in the circuit, which can be conveniently connected to measuring and recording instruments. A current transformer isolates the measuring instruments from what may be very high voltage in the monitored circuit.
Features
- Small size
- High accuracy, and good consistency,for current and power measurement
- ZMCT118F can measure the AC current upto 30 amps
- Output proportional to AC current
