Split-core current transformers provide accurate measurements of AC electrical systems and feature a removable or hinged leg for easy installation without disconnecting wires or interrupting power. Both retrofit and semi-permanent metering applications can benefit from the split-cores non-invasive design.

Split core CTs have a split in the core that allows the CTs to open and be placed around the conductor without having to disconnect the conductor or disrupt the wiring. Split core CTs may be more expensive but their convenience generally outweighs their cost when dealing with retrofit installations.

Dual core CT can be used for two simultaneous applications like metering & relay protection. In case if one winding is used & other is un-used then other winding must be short circuited to avoid high induced voltage in unused winding.

This is a mini split base current transformer; its the smallest one compared to the similar products (output 100MA).
The diameter of inner hole is 16mm, the accuracy is less than equal 0.5 grade,
Our ac sensing relay using snap joint structure, it can be fixed to the cable directly through nylon ties.
The amp transformer is with Built-in input coil; small and light, easy to install.
Fully enclosed CT, good mechanical properties and environmental resistance, strong voltage isolation capability, safety and reliability.
