Automatic circuit breaker APU30C, air circuit breaker designed to combine operating currents and to protect consumers and power supply equipment from the effects of short circuits and overloads.It can be used in networks up to 500V AC and up to 220V DC in which the calculated values of short-circuit currents do not exceed those given in the table.It is equipped with traditional thermobimetal relays (overload protection) and fast-acting short-circuit triggers (short-circuit or high overload protection).
