ND15 Series universal circuit breaker

The product description

NDW15 universal type circuit breaker (Jane your circuit breaker) and can DWXl5-630 type current limiting circuit breaker (hereinafter referred to as the current limiting circuit breaker) is mainly used to pay 50 hz, rated current 630 a, the rated working voltage of 380 v power distribution network, used for allocation of power and protect circuit and power supply equipment overload, under voltage and short circuit or to protect the motor overload, owe voltage, short circuit, also used in the 660 v power distribution network is used as the protection.In addition, the circuit breaker can also be used in ll40V distribution network for the above protection.

Circuit breaker (current limiting circuit breaker) in addition to fixed structure, also has a draw-out type structure, under normal conditions can be used as circuit infrequent conversion and motor infrequent starting, because the circuit breaker has two or three section protection characteristics, can be selective protection of the power grid.Drawer type circuit breaker (drawer type current limiting circuit breaker) in the main circuit and secondary circuit are used in the insertion structure, omit the fixed type of the necessary isolator, do one machine two use, improve the economy of use, and bring great convenience to the operation and maintenance, increase the safety and reliability.In particular, the main circuit of this drawer can be universal with NT3 fuse block, so that in emergency state can be directly inserted into the fuse power supply.

Due to its current limiting characteristics, current limiting circuit breakers are especially suitable for networks where there may be too short circuit current.

Circuit breakers are designed, manufactured and inspected according to GBl4048.2.
