The Wöhner 33506 is an advanced three-pole NH fuse switch-disconnector with integrated electronic fuse monitoring, designed for safe switching, isolation and overcurrent protection in industrial low-voltage power distribution systems. As part of the proven QUADRON® 60Classic Speed range, it combines dependable switching performance with continuous fuse status monitoring to minimise downtime and simplify maintenance.
The unit features an operator-independent snap-action switching mechanism with double-breaking main contacts, ensuring consistent switching regardless of operating speed. Integrated electronic fuse monitoring enables rapid identification of a blown fuse, helping maintenance engineers reduce fault-finding time and improve system availability.
Designed for NH size 000 and NH size 00 fuse links, the Wöhner 33506 has a 125 A rated current and is suitable for systems operating at up to 690 V AC. The bottom box-terminal connection integrates directly with Wöhner 60Classic busbar systems, making it ideal for industrial switchboards, motor control centres and OEM machinery.
Integrated electronic fuse monitoring provides immediate indication when a fuse has operated, enabling maintenance personnel to identify faults quickly and reduce unnecessary troubleshooting. This helps improve equipment uptime while supporting efficient preventive maintenance programmes.
The Wöhner 33506 also incorporates double-breaking main contacts, a spring-controlled switching mechanism and CrossLink® adapter technology, delivering reliable switching performance together with rapid installation on Wöhner 60Classic busbar systems.
