● AKH-0.66/H series current transformer
Function
Large capacity with IP65 protection rating, suitable for low-voltage measurement on the transformer side. The protection class can reach 10P20, providing effective short-circuit or overload protection for motors. The square window allows busbar passage. Generally used with relay protection; can be used with the ARD3T motor protection unit and ALP line protection, and can also be used with ABB's SPAJ140C relay.
Applications
Transformer low-voltage measurement
