And its modifications are produced at the facilities of the Russian company Incotex-SK LLC.

The main activity of this company is the production of electricity meters, ranging from the simplest single-phase electricity meters type Mercury 201, Mercury 200.02 and ending with complex multi-profile, three-phase, industrial electricity meters such as Mercury 230, Mercury 234. The Mercury brand has been known to consumers since 2001.

We all remember the old black electricity meters with a spinning disk that calculates the consumption of electricity by a "rumbling" counting mechanism at night. But time goes on, everything changes, and the means of energy metering change accordingly. Now you almost never see old morally and technologically obsolete counters. They were replaced by more advanced models. Electric meters of the Mercury 201 series are just these representatives.

The Mercury 201 series Mercury 201 is represented by several modifications and has the following specifications 201.2, 201.22, 201.4, 201.5, 201.6.

They differ from each other depending on the permissible operating current, as well as the method of displaying information.

Design features Mercury 201.5

All representatives of the 201 counter series are made in the same rectangular plastic case. On the front panel of the device (on the left side) there is an LCD display for displaying information (or "drums" for calculating electricity), on the right - a "tablet" with the main technical parameters. The case itself, and, accordingly, the device itself, is quite compact and has dimensions of 105x105x64 mm (weight about 350 g).

The bottom panel of the case is removable - it acts as a protection for the contacts of the device. Connection of wires to these contacts is carried out by screw connection.

As for fixing in a shield or on any other surface, the mercury 201.5 electric meter is fixed using the so-called DIN rail. Leading manufacturers consider this method of installation to be the most rational, because today most metering devices are fixed precisely due to such a rail.

Characteristics of the electricity meter Mercury 201.5

Considering the main specifications electric meters Mercury 201, it should be noted that these devices provide special protection against theft of electricity by polarity reversal. That is, it can be argued that the methods of stopping the electric meter by changing the “phase to zero”, which the Internet is full of, are simply unfounded.

The table shows the main technical characteristics of electricity meters Mercury 201

Many consumers electrical energy are faced with the replacement or installation of a new electric energy meter. There can be many reasons for replacing (installing a new one): mismatch of the accuracy class requirements for commercial accounting of the retail electricity market; expiration date, verification; mechanical damage; connection of a new garage, house, apartment and the like. Consumers are asking the question: "Which meter to install? Which one is better, cheaper, more reliable, more beautiful?". There are many offers on the market. From personal experience I note that when buying an electric energy meter, it is difficult to say which one will work flawlessly for the entire service life and will not stop in a month or a year. In my practice (more than 12 years), both very expensive ones (with GPS, etc.) and the cheapest ones (400 rubles each) stopped a few years after the installation of metering devices. So here's how lucky. Anything can happen to any counter, for this there is a guarantee.

At present, the majority of single-phase (220 V) household consumers stop at the choice of an electric energy meter. Citizens justify their choice with the cheapness of this device, small overall dimensions, good appearance, the ability to install on a din-rail in popular, inexpensive boxes.

The accuracy class of the Mercury 201.5 counter is 1, in the photo above it is the number 1 in a circle.

Before buying, you should pay attention to the date of manufacture of the meter, usually it coincides with the date of the initial verification. I came across online trade.ru dated December 8, 2015, that is, at the time of purchase they were about 3 months old - this is excellent. The manufacturer puts the production date directly on the box, you can find out without opening it, without printing it out.

You should also pay special attention to the presence of various stickers, seals, stamps, the absence of which unacceptable:

Installing this meter is very easy.

First, remove the "terminal" cover:

1. Unscrew the screw.
2. We insert, for example, a small screwdriver into the holes.
3. We take away (the bottom of the cover up) and remove the cover.

If anyone forgot the simplest circuit connections - on the cover there is a reminder cheat sheet in the form of a meter connection diagram. We connect the wires according to the diagram.

The terminal cover is perforated for easy breaks or bites, then the cover is firmly inserted and screwed into place.

The meters are designed to account for active electrical energy in single-phase two-wire networks alternating current with a frequency of 50 Hz with the possibility of multi-tariff accounting for time zones of the day. For programming and reading information about energy consumption, the meter has a digital interface. They are operated autonomously or as part of automated information-measuring systems (AIMS).
