Overview of the electricity meter Mercury 201
Design Features
By design, the Mercury 201 counter of any series has the same housing. This is a rectangular plastic case. Such a counter is screwless, thanks to which it is as much as possible protected from break-ins, moreover, the mechanism is quite tight.
In the foreground (on the front panel) is a liquid crystal (LCD) display, which displays the necessary information on the calculation of electricity. Near the LCD display (on the right side) the main technical specifications are indicated.
Dimensions of the design are compact and convenient and are: 105 * 105 * 65 mm, where 105 is the width and height of the device, and 65 is its depth. On average, the weight of the device ranges from 250 to 350 grams, depending on the series. Due to this size and weight, the mechanism can be attached to the surface without modifications to additional mounts. To the wall (or to any other surface that the consumer chooses) the counter is attached with DIN rails.
The bottom panel in the mechanism is removed. Its purpose is to protect the contacts of the device. That is, if you remove it, it will open access to the input electrical contacts of the device. The connection to such contacts is carried out using a screw connection, as shown in the photo below:
Some basic technical characteristics make the meter more convenient to use. For example, the accuracy class has a technological margin, and thanks to the use of a shunt in the circuit, you can accurately measure the DC component of the current.
The figure below shows the overall dimensions (drawing) of the Mercury 201 device.
Main and additional characteristics
Before you begin to study the technical characteristics of the device, it should be noted that the meter has special protection against theft of electrical energy by means of polarity reversal. That is, if you change the phase to zero, then the meter will still show accurate data and will not stop working.
Technical characteristics of the Mercury 201 counter differ among themselves depending on its modification. Description of models from 201.1 to 201.6, their maximum load and other parameters are shown in the table below:
In addition to the basic values, the meter also has additional technical characteristics (such as temperature range, operating conditions, warranty period and service life). They are listed in the table below:
The main difference between the devices is the fact that, in some models, the display of the consumed electricity is shown on liquid crystal displays (indicators), and in some models there is a mechanical counting unit.
Also, in some models there is a PLC – modem, with which you can record all changes in devices.
The electricity meter Mercury 201 began to be very popular among residents of private houses and apartments. The reason for this is not only technical specifications, but also an affordable price. Due to the accuracy of measurements and an affordable price, the meter has gained recognition among consumers of electricity.

Wiring diagram
Mercury counter 201 is connected to the power supply, as well as all similar constructions for metering electric energy. Only when connected, the main thing is the correct choice of conductor for input and output. The input wire is determined automatically - it will be the same as it was determined by the manufacturer and the organization of energy supply. Any wire (for example, Ball screw).
The correct connection diagram of Mercury 201 to the network is shown below:
So we examined how to properly connect this model of the electric meter, as well as the technical characteristics of Mercury 201. We hope the information provided was useful to you!
