Wohner QCB-NH00-AC-SD AC Switch Disconnector

Description:

The Wohner QCB NH00 160A 690V AC switch disconnector is used in industrial power distribution systems for switching, isolating, and protecting electrical circuits utilizing NH00 fuse links within low-voltage distribution equipment. Commonly installed in switchgear assemblies, motor control centers, industrial automation panels, and power distribution cabinets requiring high-current fuse protection and safe load disconnection. Maintenance teams, panel builders, and system integrators use this fuse switch disconnector for feeder protection, electrical panel retrofits, busbar system integration, and replacement of damaged fuse disconnect units.

Applications:

The Wohner QCB NH00 fuse switch disconnector is widely used in industrial environments requiring reliable circuit isolation and overcurrent protection for motors, transformers, feeders, and branch distribution circuits. It is commonly integrated into industrial automation systems, MCC panels, OEM machinery, renewable energy systems, and low-voltage switchgear assemblies where NH fuse technology is used to provide safe maintenance isolation, overload protection, and efficient modular power distribution through busbar systems.
