Specification

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

Standardize /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 signaling
Remote tripping of the NB1-63 DC can be realized
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
Signaling the switching state of the NB1-63DC in
the individual strings

Application

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