Description
This Iskra MT174-D2 is a 120A direct connect three phase meter manufactured by Iskra, one of Europe’s largest electric meter manufacturers. This class B, (accurate to within 1%), surface mounted meter is MID approved making it suitable for billing applications and includes two pulse outputs and an RS485 connection. While typically used in three phase four wire installations, it can also be used on both single and two phase supplies. It also logs recorded data internally so in the event of a fault, such as a screen failure, readings can still be retrieved.
We configure the auto scroll display, (viewable without having to press any buttons), on the MT174 for different applications as listed below. This ensures the key information required is available without having to check instructions, press buttons etc.
The Iskra MT174-D2 is one of the most versatile three phase meters on the market and can be configured to show a number of different electrical parameters to suit a wide variety of applications. These include billing for consumption, measuring imported and exported energy on renewable installations, logging dual rate readings for tariff’s such as Economy 7 as well as measuring most of the common electrical parameters such as Energy (kWh), Power (W), Current (I) & Voltage (V) to name just a few.

| Reading Meter | Displays Energy (kWh) Consumed | |
| Dual Tariff | Displays Energy (kWh) Consumed on Tariff 1, Tariff 2 & Total | |
| Import & Export | Displays Imported & Exported Energy (kWh) | |
| Billing | Records Energy (kWh) consumed on the 1st of each month at 0:00 over a period of 9 months | |
| Multi-Function | Displays the most common electrical parameters for network analysis | |
| Maximum Demand | Records the maximum Power (W) demand within a set time period | |
| Pulse Output | Both the pulse length and duration can be configured to suit. |
All MT174s have the following parameters available in the manual scroll display, (accessible using the blue button):
