Product Overview

YuanXing Electronics manufactures a Current Transformer for Busbar with a very high level of accuracy. The busbar current transformer has been specifically designed to provide excellent current signal acquisition optimally within a low voltage distribution system. The unit features a core made of cold-rolled silicon steel strips manufactured without any air gaps; this provides the transformer with maximum magnetic permeability. The secondary winding is wound uniformly, which provides the bus bar CT with minimal magnetic leakage and therefore makes it a trusted component for key monitoring of energy.

The busbar type current transformer has been designed to have a very broad input range (between 5 A and 6300 A) along with standard output options (5 A and 1 A) for maximum versatility within the broad range of metering options available in the industrial market. In addition, the housing is made of high-density ABS or PC to ensure that the device will operate reliably within the temperature range of -40°C to +85°C. Furthermore, the busbar current transformer can reliably operate within the frequency range of 50 Hz to 400 Hz and at an AC voltage level of 600 V with a dielectric strength of 2500 V AC/min.

The current transformer busbar type meets IEC 61869-2 standards, has an accuracy class (0.2, 0.5, or 1.0 respectively), and is available in six different sizes to be used for fixed installation (RoHS compliant). The busbar current transformer has the long-term reliability and accuracy needed to support today’s modern industrial electrical grid.
