• 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

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 theMCB tripping or manually disconnecting, all polesare isolated from the mains, the PV string can have a reliable protection.

•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.
