According to the current state standards, the RCD must have a mandatory two certificates:

certificate of conformity;
fire safety certificate.

Appropriate technical documentation must be attached to the RCD, which contains information about the technical parameters of the device, the most important:

rated operating current - In (usually these are 16, 25, 40 A);
rated differential breaking current - In (10, 30 or 100 mA);
resistance to short circuit currents - Inc;
the parameter that determines the quality of the device, it must be at least 6000 or 10 A, because others are simply unsafe to use;
performance - Tn (20-30 ms);
warranty period (serious firms give a guarantee of at least 5 years), etc.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Samsung Bespoke 4-Door Flex Refrigerator with Meal Plan and Digital Cooking 27.12.2023

Samsung Corporation introduces its new Bespoke 4-Door Flex smart refrigerator. This device has four doors, one of which is equipped with a 32-inch vertical screen. This innovative refrigerator allows you not only to order groceries, but also to watch TV shows and YouTube videos, as well as control your smart home.

Samsung Bespoke 4-Door Flex takes an integrated approach to food storage, offering not only smart features, but also innovative capabilities in nutrition planning and digital cooking. This opens a new era in the use of technology to improve everyday life and health care.

The main highlight of the new refrigerator is its built-in artificial intelligence, which can develop a meal plan for one person or for the whole family, taking into account the individual needs of each member. Neural networks take into account various factors, ranging from goals (weight loss or weight gain) to the presence of allergies or special diets.

The AI refrigerator assistant can generate recipes for a variety of dishes using ingredients available in the house. Artificial Chef understands your preferences: regular, gluten-free, pescatarian, dairy-free, vegan and more.

The refrigerator has a “vision” function, which allows the device to determine what products are stored in the chamber and warn about the expiration date. The production date must be entered manually. There are some limitations: the device currently detects up to 33 product categories.
