1, introduction
DW15 series universal type circuit breaker (hereinafter referred to as the circuit breaker) is suitable for use in ac frequency 50 Hz, rated current to 4000 A, rated voltage 380 V power distribution network, the electric energy and power supply line to distribution and power equipment overload, owe voltage, short circuit protection with. Shell frame rated current level of 630 A circuit breaker can also in communication frequency 50 Hz, 380 V network for motor overload, owe voltage and short circuit protection.
Circuit breaker in normal conditions can be used as the frequent changeover not line, with shell frame rated current level of 630 A circuit breaker also has the upper structure and the current limit circuit breaker in normal conditions can be used as A motor starting with less frequent.
The current limit because of the limited flow characteristic circuit breaker, especially suitable for possible big short circuit current network.

2, the use,
DW15-630 universal type rated current of the circuit breaker since 100 A and 630 A, rated voltage ac 50 Hz380V, mainly in the circuit breaker in distribution network distributed electric energy, protect lines and power equipment overload, owe voltage and short circuit. Also can be in exchange Hz380V 50 in electric motor used to protect the overload, owe voltage and short circuit. In normal conditions, circuit breaker can be used as the transformation and frequent line motor starting with less frequent.
DW15-1000 A ~ 4000 A low voltage universal type rated current of the air circuit breaker since 630 A and 4000 A, rated voltage ac 50 Hz380V. Mainly in the distribution network for distribution of electric energy and protecting circuits and power equipment overload, owe pressure and short circuit protection, in normal conditions can be used as a line of the use of frequent changeover.
