MES Current Transformer

Q: How much headroom should I leave on the power rating?

For continuous industrial duty plan on 20-30 % headroom above the measured load. For loads with high inrush, such as motors or capacitive input, allow more and check the surge rating rather than only the average current.

Q: Do these units accept 110 V and 230 V mains?

Input ranges are model-specific and shown in the specification table. Where a wide-range input is available it is stated; otherwise send your mains voltage and we will match the model.

Q: What protection features are built in?

Typical protection covers short circuit, over-current, over-voltage and thermal shutdown. The exact set is listed per model in the specification table above.

Q: Can you supply matching DIN-rail or enclosed versions?

Open-frame, enclosed and DIN-rail variants exist across this family. Send the model you are working from and we will confirm the equivalent mounting option.

About the MES Current Transformer

The MES Current Transformer is part of the ELEHPD Current Transformer range. MES Current Transformers The MES series of current transformer have beautiful outline and Convenient for mounting in many ways. The most current transform need the special mounting and the MES series used the mounting of DIN typing With a lot of times. The protective cover for the terminal block used the switching device with Safety and quick. MES guide rail type CT: Primary current: Secondary cur ELEHPD manufactures and exports low voltage electrical products from Yueqing, Zhejiang, China, supplying distributors, panel builders, M&E contractors and OEM buyers worldwide.

Typical applications

Industrial control panels and PLC power rails
LED drivers, signage and display power
Battery charging and DC backup systems
Motor drives, welding sets and rectifier assemblies
Instrumentation and test equipment

How to specify the right Current Transformer

Size the output current with at least 20-30 % headroom over the load
Check the input range covers the local supply, including brown-outs
Confirm the enclosure and cooling method for the panel temperature
Verify the protection set: over-current, over-voltage, thermal and short circuit
