Current transformers (CT’s) are used for the measurement of electrical currents. When the current or voltage is too high to be directly applied to a measuring instrument or device, a current transformer will produce a proportionally reduced current which can be directly applied to the measurement device.
 
Current transformers are commonly used in metering applications and in the electrical power industry.
 
Aurora Current Transformers are UL / CSA Approved.  You save money buying them here because we buy in bulk. We use this component in our diesel generators so our controllers and or gauges can display the load applied to a generator and the power in watts being consumed by end users.  
 
This current transformer is rated  for  200A:5A
