Air - circuit Breaker
Product Overview
DXW15 series universal - type circuit breakers (hereinafter referred to as circuit breakers) are applicable to AC 50Hz, with rated currents ranging from 200A to 4000A, and rated working voltages of AC 380V to 1140V power distribution networks. They are used for over - load, under - voltage, and short - circuit protection of power distribution energy, power supply lines, and power source equipment. They can also be used for over - load, under - voltage, and short - circuit protection of motors in AC 50Hz, 380V power grids.
Under normal conditions, the circuit breaker can be used for infrequent switching of lines, and under normal conditions, it can also be used for infrequent starting of motors. The circuit breaker with a shell - frame rated current of 630A also has a draw - out type structure and a current - limiting circuit breaker.
Due to its current - limiting characteristics, the current - limiting circuit breaker is especially suitable for networks where large short - circuit currents may occur.
It complies with standards GB14048.2 and IEC60947 - 2.
