Web25 Mar 2024 · This part of IEC 62271 specifies circuit-breakers designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V. It is only applicable to three-pole circuit-breakers for use in three-phase systems and single-pole circuit-breakers for use in single-phase systems. WebA circuit breaker is defined as, switching device which interrupts the faulty current and performs the function of a switch thus protecting the electrical system from damage. Working Principle of Circuit Breaker There are two essential contacts in a circuit breaker, and they are: Fixed contacts Moving contacts changan contact number
