Circuit Breakers

When operating the aircraft electrical network, the most frequent faults are short circuits in consumers and networks, overloading of consumers (for example, electromechanisms with increasing torque on the shaft) and wire breaks. To prevent serious consequences of emergency conditions in the circuits of the electrical network, protective equipment is installed. The three-phase alternating current circuit breaker is designed to protect the electrical equipment of AC networks from the dangerous overload and time-consuming overloads. Automatic protection are installed in cabins with red lighting and are characterized by an elongated handle and the absence of a glowing eye on it. Automatic network protection АЗ3, АЗК1, АЗК3, АЗФ1, АЗР, AZS - electrotechnical single- or triple-pole automatic circuit breakers, providing protection of electric circuits from the effect of current overloads and short-circuit currents. At the same time, the circuit breakers are three-pole switches. Automatic filling stations are structurally composed of upper and lower knots, handles and covers with three self-locking nuts. The upper assembly includes a plastic upper housing, inside which there is a contact mechanism and movable contacts. General dust and moisture protection is provided by the seal assembly and rubber gasket, dustproof and moisture resistant.
