1. Product feature
AKH-0.66S series double-winding current transformers have two secondary windings. One winding (1S1, 1S2) is used for ammeter indication and the rated current is 5A or 1A AC. The other winding (2S1, 2S2) is used for remote measuring and matches with ARTU-M2 remote measuring unit or ARD3 motor protector. The rated current is 20mA AC. The linearity of double-winding current transformers is increased to 8 times. When the actual current is 8 times higher, the error of double-winding current transformer is still maintained between 0.2% and 0.5%. Therefore, they can be used in the motor protection circuit.
The housing is fitted with flip-open cover and made of 120℃ flame-retarded PC by injection molding. The iron core is cold-rolled silicon steel belt. The secondary lead is the high-strength enameled magnet wire. The product has the novel structure and nice appearance and is easy for installation. It features the small size and weight, good accuracy and large capacity.
