purpose
The DWX15 series universal current limiting circuit breaker has a rated current of 630 amperes and a rated working voltage of 50HZ380V AC. It is used for distributing electrical energy in distribution networks, protecting lines and power equipment from overload, undervoltage, and short circuit, and can be used for infrequent line switching under normal conditions. Circuit breakers can also be used to protect motors from overload, undervoltage, and short circuits, and can be used to prevent frequent starting of motors under normal conditions.
The DWX15C series drawer type universal current limiting circuit breaker has a rated current of 630A and a rated working voltage of 50HZ380V AC. In addition to the features of the DW15 series, the drawer style installation structure improves the economy of use, and plug-in structures are used in both the main and secondary circuits. In the complete set of equipment, the necessary fixed isolation switches can be omitted, achieving one machine for two purposes. At the same time, it brings great convenience to operation and maintenance, increases safety, reliability, and flexibility in emergency situations. Circuit breakers have limited current characteristics and can quickly disconnect in the event of a large short-circuit current, making them particularly suitable for use as protection in networks where large short-circuit currents may occur.
