CHINT DC BREAKERS NB1-63DC SERIES

Specification

Rated voltage up to 1000V, Rated current up to 63A;

Standard:IEC/EN 60947-2 ,RoHS

Features
Hight breaking capacity
Connection type :Wire and busbar
Storage operation make on/off faster
Installation and disassembly convenient
color coded contact position indicator provides 
 visual indication of the device status and insulation function.Protection of circuits against overload currents;
Protection of circuits against short-circuit currents;

•Remote tripping and signalling
Remote tripping of the NB1-63 DC can be realised 
with an under-voltage V9 or shunt operation 
release S9.
An optional auxiliary (on or off) XF9 or signal 
contact XF9J (over-current or short circuit) signals 
the actual switching state of the 
device in the individual strings.

•DC load disconnecting switch
Safe switching under load. In case of faults or 
maintenance work, individual strings can be 
safely and selectively switched under load.
The NB1-63DC has the function of isolation 
switch. For ungrounded power grid, in case of the 
MCB tripping or manually disconnecting, all poles 
are isolated from the mains, the PV string can 
have a reliable protection.

•Advantages and benefits
Can be operated up to 63 A and 1,000 VDC
Safe switching and disconnecting of individual 
strings under load
Selective remote tripping of individual strings 
under load
Signalling the switching state of the NB1-63DC in 
the individual strings

Application

NB1-63 DC circuit-breakers are used incommunication systems and PV DC systems.
