FL-2D DIN43703 Switchboard Shunt

FL-2D Shunt - DIN43703 Shunt

The FL-2D type shunt is a DIN43703 shunt that has been improved and named FL-2D by our company for easier model selection and identification by users. This series of products complies with the DIN43703 standard.

The shunt is widely used to extend the current measurement range of instruments. It includes fixed-value shunts and precision alloy resistors, which can be applied in communication systems, electronic devices, and power circuits for automation control, serving as current limiting and current balancing sampling detectors.

To ensure high-quality products for customers, the company selects premium manganese-copper alloy sheets. The product utilizes copper-silver-phosphorus solder, resistance contact welding, and fusion welding to ensure a reliable manufacturing process. Each product undergoes rigorous testing and screening before leaving the factory.
