About the Product

Protected with Araldite® epoxy sap and expected for the primary board or the engine control board framework, every one of these current transformers for indoor use has a busbar terminal and is intended to be utilized related to estimating or observing instruments, or with defensive transfers.

The two-center is accessible with an essential current rating of 500～3000A. When presented with an evaluated essential current of 800A or over, this model has an additional tap in the optional winding and can be utilized as a double proportion CT.

These current transformers are dampness safe and precisely strong, while giving brilliant electrical execution.
