Differential current switch EKF ELCB-2-32-30-Pro 2P, 32A, 30MA, type AC

In any house there is an extensive network of cable communications. Electric wires differ in the diameter of the section, the method of laying, permissible voltage and quality of insulating materials, and each conductor has its own permissible current load. This indicator characterizes the thermal resistance of insulation. The parameter of the permissible current load shows the excess of what value of the electric current will become critical for the conductor. Particular attention should be paid to this characteristic when organizing an electric network, since overload can lead to fire and exit of the wiring. The reason is that when the current exits the current value of the load, the wire overheats and the destruction of insulation occurs. Another danger to the electric network is the risk of short circuit in case of violation of the insulation of the wiring. During a short circuit, a sharp increase in current strength occurs, as a result of which the permissible current load is many times higher, an electric arc appears, and the cables and wires are quickly overheated. Overloads and short circuits pose the most serious danger to any electrical network and all equipment connected to it. Therefore, the mandatory requirement is the installation of protection devices - automatic circuit breakers.

Only machine guns are not enough to ensure complete protection of the electric network. The threat to health and life arises in cases where a person touches the metal surface of the electrical appliance, the body of which was energized as a result of a malfunction. In order to protect a person from receiving a shock, it is necessary to use special devices for protection against current leakage.

To install on Din races in camshaft, automatic circuit breakers and other devices for protecting home electric circuits are produced in modular design. < /p>
