Voltage relay 220 for the house: the principle of operation, the device

Unbalance between phases, unstable mains voltage, alas, the reality of many apartments. Weak transformer stations often can not cope with the heavy load. Particularly urgent is the problem in private homes. adjoined wire, A sharp voltage drop, and voila - you risk being left without a stable running of household appliances, as well as there is a danger of electric perekala. The solution of such problems is to install the relay voltage 220 Housing, which will ensure the protection of electronics in unstable electrical load.

voltage relays - what is it and what is used

voltage relays will protect your network from power surges, including those associated with the erroneous connection of phases. Without special protection network is simply not withstand the drop.

It is very handy in the event that your electrical devices require a certain load on the network.

The principle of operation of voltage relays and device

Once the device detects drop in the network, your home will be de-energized at the same instant.

Ask a Question

«Do not confuse the RCD and ILV - the task of these devices have fundamental differences. For ILV may fail if the network drop are in an acceptable range. "

voltage control relay 220 for the house and its additional features

Unlike RCDWhich oscillation is triggered when any network voltage relay (a maximum range of 220 to 280 The minimum - 190-210 V, can be configured to automatically trigger when certain values. Furthermore, the device can independently resume supply after a certain time, which may not usual fuse. The time interval ranges from 3 to 900 seconds.

Separation on PH types based on the type of connection and install

Various modifications ILV or types of devices. They differ in characteristics and the set of parameters.

Relays of voltage in the socket: a conventional adapter, protecting equipment

Relay voltage and current essentially looks like an adapter in socket. This attachment can protect what that particular device that you connect to it.

How to connect voltage relay in the form of extension

Relay protection against voltage surges can be produced in the form of extension that allows the connection multiple instruments, but their total maximum current should not exceed 16 A (as is the case with relay socket).

ILV installation on DIN rail

Relay 220 V DIN Rail is able to protect all the electrical appliances in the apartment or private home. It is important to correctly calculate the allowable values ​​of the network load. And devices to select on the basis of this parameter.

Important! The total amount of consumed current should normally not exceed the allowable value. Each device its borders.

Why are single-phase and three-phase voltage relay 220 for the house: types of devices

There are cases when the network require different kinds of stress. In this case, you need to set a different layout in a special distribution board. Each type of network voltage the relay will act on its circuit.

Single-phase voltage relay control and its field of use

They are connected to a power supply with a certain load. So, set the relay, if necessary, for three-phase networkMore profitable to install three-phase relay.

Three-phase ILV: setting benefits at a voltage of 380 V

If the house comes to power 380 is the need to protect the three groups that will be powered from it, you can install three-phase ILV.

Criteria for selection of the voltage monitoring relays for an apartment or private house

The main criteria for selection of such equipment are:

• run pickup range;
• presence of thermal protection;
• stock rated current readings;
• the presence of the screen voltmeter.

General advice on how to connect voltage relay

Features of the connection, of course, depend on the brand of the device. Most often it is below 3 terminals, Which connect the wires in the following order:

• contact №1 - neutral conductor, connectable branching from the main wire or simultaneously input / output;
• contact №2 - Power input (phase conductor) extending from the metering device;
• contact №3 - phase output for further distribution.

Additionally, each unit is supplied with detailed instructions for the connection. A variation can be very different.

Popular models voltage monitoring relays: setup, installation scheme

On the market today there are many options such equipment. We would recommend to stay on the Russian producers or manufacturers, proven.

Where to buy voltage relays for home monitoring

Buy Voltage relay Housing 220 can be in any specialized shop. In addition it is possible to order the equipment through the Internet. However, in this case, you lose the opportunity to check the quality of the product prior to purchase. In this case, the purchase of a guarantee of quality can become independent reviews of Internet resources.

The device is quite useful, but requires care and thoughtful use. Therefore, before buying a voltage relay, examine the parameters of your network.
