The Wöhner 33516 is a high-performance three-pole NH size 1 fuse switch-disconnector with integrated electronic fuse monitoring, designed for safe switching, reliable isolation and overcurrent protection in industrial low-voltage power distribution systems. Part of the proven QUADRON® 60Classic Speed range, it combines dependable switching performance with intelligent fuse supervision to minimise downtime and simplify maintenance.
Featuring an operator-independent snap-action switching mechanism and double-breaking main contacts, the Wöhner 33516 provides fast and consistent switching regardless of operating speed. The integrated electronic fuse monitoring continuously supervises the condition of installed NH fuse links, enabling maintenance personnel to identify blown fuses quickly and restore equipment to service with minimal interruption.
Designed for NH size 1 fuse links, the switch-disconnector is rated at 250 A and mounts directly onto compatible Wöhner 60Classic busbar systems using CrossLink® adapter technology. Its robust bottom M10 screw terminals provide secure cable connections, making it ideal for industrial switchboards, motor control centres, OEM machinery and main power distribution installations.
The integrated electronic fuse monitoring continuously supervises all installed fuse links and provides immediate indication when a fuse operates. This allows maintenance engineers to identify faults quickly, reduce diagnostic time and minimise costly production downtime. The monitoring system is particularly valuable in industrial environments where uninterrupted operation is critical.
Combined with Wöhner's proven spring-controlled switching mechanism and double-breaking contacts, the 33516 delivers dependable switching performance together with enhanced maintenance safety. CrossLink® adapter technology enables fast, secure installation while ensuring reliable electrical contact with compatible 60Classic busbar systems.
