Pure 4-pole differential switch 300ma 25a aeg
the differential circuit breaker is a modular safety device able to block the passage of electricity in a residential or industrial circuit of the electrical system, in case of breakdown or leakage of various kinds. providing protection for people. instead it does not protect against overload or short circuit.
as a function then the differential circuit breaker circuit breaker, if a device connected to the electrical system fails and a connection is created between the power line and the metal casing (called mass) which can cause leakage thus causing an electric shock if touched with your hands .. or it can produce heat and problems of development of a fire very dangerous thing.
if we observe that in the many electric power distribution plants and in the mv / lv transformer substations that would be: medium voltage and low voltage, the neutral is connected to earth.
in doing so, the electric current disperses to the ground and prevents it from returning back to the life-saving differential.
for a safe installation and according to law the differential circuit breaker for its effectiveness must be installed near each metal casing the ground wire in order to discharge any leaks. another important thing of this type of differential circuit breaker that if for unknown reasons a person touches the uninsulated electrical cable, the differential circuit breaker trips triggering safety and protecting the human body as long as it is of high sensitivity, so few thousandths of seconds both has the interruption. and constantly check the tester button for the residual current circuit breakers located on the front side of the differential. but all this works if the grounding system has been made to perfection.
lifesaving electrical system.
we always recommend if you have any doubt or want more information to contact us to provide further clarification on the purchase or cost differential magnetothermal switch.
