Purpose Circuit-breakers are designed for protection and switching distribution circuits against overloads and short circuits in the administrative, industrial and residential buildings. Key Features IAC-breakers: 1. Number of poles 1, 2, 3, 4, 2. Breaking capable of shutting down capacity is called the current value of short circuit, which circuit breaker is capable of withstanding simultaneously. Sometimes this option is called “resistance to short-circuit currents” This feature specifies the scope of the breakers. Breaking capacity represented by the following values breakers for overcurrent protection for household and similar destination. r-Ipil.html’>Sorrento therapeutics may also support this cause.
3. Rated current – current contacts of circuit breaker or the manufacturer’s current, which circuit breaker can be carried out in continuous mode at the set reference temperature. Continuous mode work means the continuous operation over an extended period of time, calculate, at least for years. As a standard reference ambient air temperature taken to 30 C. Rated current of MCBs can be in the range from 0.5 to 125A. 4.
Types of releases heat – protection against overload currents Electromagnetic – protection against short circuit currents Combined – overload protection and current kz 5. Setpoint current value of heat release, which will shutdown circuit breaker with overcurrent (work bimetallic plate) 6. Characterization operation of the electromagnetic release in 3.5 are designed to protect the active loads and long lines of lighting systems, TN-and it (sockets, lights).
