FAQ

1. How do I select the right DX current transformer for my cable or busbar?

Select the DX current transformer according to the primary current, conductor dimensions and available installation space. DX-20, DX-30, DX-40 and DX-125 offer different window sizes and electrical configurations. Confirm that the cable or busbar fits the selected window, and check the dimension drawing before ordering.

2. How do I choose the current ratio and secondary output of a DX current transformer?

Choose the current ratio according to the circuit’s normal operating current and maximum expected current. The secondary output must match the connected meter’s CT input. The DX series lists 1 A and 5 A outputs; confirm availability for your selected model and ratio before ordering.

3. What accuracy classes and rated burdens are available for DX current transformers?

The DX series lists Class 0.5 and Class 1.0, with available rated burdens depending on the model and current ratio. Select a configuration that meets your measurement requirements and accommodates the total secondary burden, including the meter, connecting cables and connections. Confirm the specific accuracy and VA rating when ordering.

4. What is the purpose of the DX current transformer’s double terminals and short-circuit links?

The double-terminal arrangement supports convenient secondary connections and the fitting of short-circuit links for instrument maintenance. Before disconnecting a meter while primary current is flowing, qualified personnel must safely short-circuit the CT secondary using the appropriate arrangement. Never leave an energized CT secondary open-circuit. Confirm whether short-circuit links are included with your order.

5. What information is required for a DX current transformer quotation?

Please provide the required current ratio, secondary output, accuracy class, rated burden, cable or busbar dimensions, and order quantity. Include the preferred DX model, installation requirements and any required certificates or test reports. A conductor drawing or panel layout can help us recommend a suitable configuration.
