Current transformers are indispensable in many places.

Müller + Ziegler offers tailored solutions for your current transformer needs too.

Our numerous products include current transformers of accuracy classes 1 and 0,5. However, if you require current transformers of higher accuracy classes, this is possible without any problems, on request. We have specialised in developing special solutions to satisfy individual customer wishes. Thus, not only are current transformers of higher accuracy classes but also certified transformers or models for DIN rail mounting are available on request.
The rated power available at the secondary terminals is stated in VA. The choice of rated power as well as the measuring range itself are determined by the consumption of the particular meter that is connected to the current transformer, including the measuring wires. The consumption of the measuring wires is dependent on its length. Hence cparticularly high consumption arise in the case of a long measuring wire and secondary currents of 5 A. If the length of the measuring wires cannot be altered, current transformers with a 1A secondary current are recommended to minimise the consumption that arises.

Diverse current transformers from our wide product range

We are able to offer you a wide choice of current transformers for diverse purposes. Besides plug-in current transformers we can also supply wound primary current transformers, summation current transformers and split-core current transformers. Which model of the respective category is best suited for use in your company is dependent on numerous factors. In general it should be borne in mind that with plug-in current transformers with a lower transformation ratio, the output power in VA falls as well. Through repeated passage of the primary conductor, a smaller ratio can be achieved for unaltered output power (VA).
When using the current transformer always be aware that hazardous voltages may be present on exposed secondary terminals and therefore “exposed working” should be avoided without fail.

Current transformers and much more – Müller + Ziegler is your point of contact for all types of electrical measurement

In addition to diverse current transformer models, we also offer a large choice of other products which are ideally suitable for use in switchboards, machine and control engineering, the wind power industry and automation technology. From diverse meters such as analogue or digital panel meters or universal meters through to energy meters you can obtain all of the electrical measuring equipment your company needs from us. As our customer, we give priority to your individual requirements. We look forward to receiving your enquiry!
