DW3-1600 series of ultra-small circuit breaker rated voltage of AC 50Hz, rated voltage AC400V, AC 690 power distribution network, used to allocate power lines and power supply and protection against overload, under voltage, short circuit, and single phase hazards such as fault. Core components of the use of intelligent circuit breaker controller with precise selective protection, to avoid unnecessary power outages and improve reliability
DW3-1600 series of ultra-small circuit breaker standard
IEC60947-2 DB14048.2 low-voltage circuit breakers
1.Innovative force interrupter device to overcome the shortcomings of traditional interrupter device. Breaker closing operation, the moving contact to drive the rapid downward movement into the insulation barrier and static contact between the moving contacts, the arc cut off by force, then off, greatly improving the breaking capacity circuit breaker
2.DW3-1600 ultra-compact frame breakers can be divided into two kinds of fixed and drawers, the whole was “with” font, layout arrangement for the three-dimensional form, with compact structure, small size and structural characteristics
3.dimensions compared with 3P/2000A
