PCB Mounting High- Precision Current Transformer 1:3000 10A/3.33mA
Type: PCB Mounting Current Transformer
Fullstar P/N : CT21FC-10A/3.3mA
Principle of current transformer is based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and a winding. The primary winding turns is less and connected in series in the circuit to measure the current, so it often flows all current in circuit; Secondary has more windings and connected in series of measuring and protection circuit. When current transformer is in operation, the two- loop is always closed. Therefore, measuring and protecting loop-circuit impedance in series with the coil current transformer is very small, close to the state of short circuit.
