As you can see, the Vemer Energy-400 D90 is a very similar product to the EKM-ET440 and the Iskraemeco CE104-R2. All three products are DIN rail-mounted three-phase energy meters with a current range of 10 to 100 A and an accuracy class of 1. They also all have LCD displays with 7+5 digits and pulse outputs. The main difference between the three products is the voltage range. The Vemer Energy-400 D90 can only be used with voltages of 3x230 (400) V AC, while the EKM-ET440 and the Iskraemeco CE104-R2 can be used with voltages of up to 3x400 V AC.

In terms of price, the Vemer Energy-400 D90 is typically more expensive than the EKM-ET440 and the Iskraemeco CE104-R2. However, it is important to note that the Vemer Energy-400 D90 has a slightly higher accuracy class (1 vs. 2).

Ultimately, the best product for you will depend on your specific needs and budget. If you need a three-phase energy meter with a current range of 10 to 100 A and an accuracy class of 1, and you are only concerned with voltages of up to 3x230 (400) V AC, then the Vemer Energy-400 D90 is a great option. However, if you need a meter that can handle higher voltages, or if you are on a budget, then the EKM-ET440 or the Iskraemeco CE104-R2 may be better choices.
