The presence of electricity in a residential, commercial building and manufacturing plant is considered the norm. But in order for the electrical communications system to work properly, it must consist of high-quality components. Even the usual power cable vvgng ls 5x10 price which is fully paid off by its reliability, must be correctly combined with connected energy consumers.
Motor protection
Most of all, it is not the switch itself that suffers from a sharp voltage drop during switching on and off, but the electric motor. As numerous studies have shown, if special protective and actuating equipment is not included in the circuit, the engine will have to be changed or repaired quite often. To avoid additional waste, the following accessories are included in the chain;
- Start buttons sized for the appropriate load.
- Modern modular contactor abb esb 20 11 or similar.
- Special soft starters for maximum protection.
- Automatic fuses or circuit breakers.
- Additional electrical equipment.
An electric motor, as a rule, does not operate with a constant, but with a variable load. If so, he especially needs additional protection factors. A well-thought-out system will ensure the performance of the motor with any permissible overloads. Including in the event of an emergency stop.
Automatic devices instead of fuses
Modern circuit breakers are a symbiosis of a conventional knife switch or a safety system. It can work in different ways, but the result will be the same. In case of significant overloads or a short circuit, an almost instantaneous network break occurs in order to prevent an emergency. It is worth adding to the advantages of modern machines:
- maximum ease of daily use;
- classic solves connection issue;
- a long service life spanning decades;
- no need for maintenance;
- return to working condition with one hand movement.
Unlike classic fuses, automatika iek va 47 29 buy would be the correct solution. Since after the next operation they do not need to be repaired or changed. It is enough to mechanically restart the system, and it is again ready to serve as a reliable barrier to a short circuit or excessive overload of any connected consumer of electricity.
