    The AKH-0.66/S series has two secondary windings. The first winding (1S1, 1S2) provides a 5A or 1A AC output for current indication. The second winding (2S1, 2S2) provides a 20mA AC output for remote measurement and can be used with an ARTU-M32 remote I/O unit or an ARD3 motor protector. The series remains linear up to eight times rated current and maintains an error of 0.2-0.5% at eight times rated current, making it suitable for motor protection circuits. Its flip-cover housing uses flame-retardant, high-temperature-resistant material, while the core is wound from cold-rolled silicon-steel strip. The design is compact, lightweight and convenient to install.
