Description
The NH bar-type switch integrates a current transformer with a fuse switch in one device. It is a compact solution for switching, isolation and fuse protection in modular busbar systems, and can serve as a main incoming switch, with an instantaneous breaking capacity up to 100 kA and load-break operation up to 1.3 times the rated current.
Design and features
- Integrated current transformer and fuse switch.
- Knife-edge entry and an arc-extinguishing device for safe operation.
- Optional isolating blade, full-range protection and semiconductor fuse.
- Fuse monitor and signal switch available; self-closing fuse inspection hole.
- Instantaneous breaking capacity up to 100 kA; load-break up to 1.3 times rated current.
Where it fits
- Modular busbar systems and main incoming switching.
- Low-voltage distribution boards needing compact, high-breaking protection.
- Industrial and infrastructure power distribution.
Selection and ordering
Confirm the rated current, the required breaking capacity, the fuse type and whether an isolating blade, full-range protection or semiconductor fuse is needed. We will confirm the correct configuration and provide a quotation.
