3-pole, for busbar systems with 185 mm center-to-center distance.
The NH In-line Fuse-Switch Disconnectors with Electronic Fuse Monitoring combine overcurrent protection, switch disconnection and electronic fuse monitoring in a single device for RiLine busbar systems.Designed for modern low-voltage power distribution systems, these NH fuse switch disconnectors combine reliable protection, safe isolation and electronic fuse monitoring in a compact design.
Each switch-disconnector continuously monitors the status of the installed NH fuse links through an integrated electronic monitoring module. When a fuse link operates, the monitoring system immediately detects the condition and provides a status indication, helping maintenance personnel locate faults quickly, reduce service time and improve the availability of low-voltage power distribution systems.
The product range includes NH00, NH1, NH2 and NH3 versions with rated currents from 160 A to 630 A, providing a suitable solution for a wide variety of industrial power distribution applications.
