DW45 series intelligent air circuit breakers are applied for the network circuit of AC 50Hz, rated voltage 400V, 690V and rated current between 400A and 6300A. Mainly used for distributing energy and protecting the circuit and power supply device against short circuit, under voltage, single-phase ground fault, etc. The HW8 has intelligent protection function and the key parts adopt intelligent release. The release can make the accurate selective protection, which can avoid cutting off the power and improve the reliability of power supply.
The products conform to IEC60847-2, IEC60947-4 standards.
Intelligent, zero arc, with isolation function;
High breaking and short-time tolerance;
With overload long delay, short circuit short delay, short circuit instantaneous and ground fault function (optional);
Drawer seat has three position indications of "connection", "test" and "separation";
CAN realize intelligent network monitoring, can be applied to Modbus, Profibus, Devicenet, CAN and TCP communication protocols, convenient for users to integrate management;
It can be equipped with FDM3 short message notification module to realize remote alarm and monitoring.
