Split-Core Current Transformers
CT251 SERIES
TP series openable current transformers are mainly used on busbars to transform loop currents and isolate strong currents.
The product has a reasonable structural design, a rectangular magnetic circuit, neatly wound secondary windings, and is opened at one end. When installing, first put the transformer winding part on the busbar, and then install the auxiliary part in place, so that the product can be installed in a relatively narrow environment.
The product uses a high-permeability silicon steel core and is precision-processed. The winding uses high-quality enameled wire, and the product performance is perfectly reflected.
This series of products has 5 sizes and specifications, which can measure cables with a current range of 100A-2000A. According to the requirements, the accuracy can be 0.5, 1.0, etc., and the secondary output signal is a standard current of 5A/1A.
When installing the product, the secondary circuit needs to be well connected before installation. During and after the installation, the secondary output of the transformer is not allowed to be open. The open circuit protection circuit part can be added inside the product as needed.

The product shell color can be produced according to the customer's specified color to meet different color schemes.
