Solutions for earth leakage protection and circuit breakers with automatic reclosing system
Technology for energy efficiency How to enhance electrical quality and continuity for your infrastructures or services by ensuring electrical protection
Nowadays, our industrial production processes Clearly, this is the correct decision. Safety and the myriad of services for individuals normally comes first, even though we cannot leave entail a constant demand for electrical energy. our installations without electric service indefinitely, especially infrastructures, Electrical service continuity ensures high production processes or services with low or energy management efficiency in our zero maintenance. companies and quality of life for individuals in their homes or places of entertainment. These types of applications make it necessary to use intelligent automatic reclosing protection When dealing with electrical protection, one devices. This implies devices that guarantee of the most frequently used solutions for protection that activated only when the problem protection devices is to cut off the electric is real, and that have the capacity to re- supply from affected areas when an insulation establish the electric supply under the reclosing fault is detected. Therefore, we are faced with conditions required by the application, which a critical electric supply continuity point, can be activated or programmed according to given that services and production processes our criteria. are interrupted to protect people against electrocution, or property against fire hazards or other damage.

The use of earth leakage protection devices with automatic reclosing was al- ready established in Low Voltage Directive ITC-BT-09, which refers to external lighting installations in the section on protection, measurement and control panels (in Spain). The same section also refers to the trip threshold regulation in relation to the earthing resistance measurement during the commissioning of an electric installation service.
Disconnection threshold of the Ohm Value of the earthing earth leakage protection resistance less than: Ethernet 300 mA 30 Ω
500 mA 5 Ω TCP2RS+ 1 A 1 Ω
RS-485 Our units can be linked to circuit breakers/rearms that are used for the lighting drive system. In turn, these elements are usually governed by timer or photo- electric switches.
