The Wöhner 33505 is a premium three-pole NH fuse switch-disconnector designed for safe switching, circuit isolation and overcurrent protection in industrial low-voltage power distribution systems. Part of the advanced QUADRON® Panel Speed range, it is engineered for panel builders, OEMs and machine manufacturers requiring dependable switching performance with convenient external door operation.
Featuring an operator-independent snap-action switching mechanism with double-breaking main contacts, the Wöhner 33505 provides consistent switching regardless of handle speed. It is specifically designed for use with a door coupling rotary handle, allowing safe operation from outside the enclosure while maintaining high standards of operator safety. The double-breaking design also enables quick, tool-free fuse replacement and provides a visible isolation gap when the cover and fuse carriers are removed.
Designed for NH size 00 fuse links, the Wöhner 33505 has a 125 A rated current and operates at up to 690 V AC. Its robust box-terminal connection and compact panel-mounted construction make it ideal for industrial control panels, switchboards, motor control centres and OEM electrical equipment.
The Wöhner 33505 combines fused overcurrent protection, reliable load switching and safe electrical isolation in a compact panel-mounted device. Its spring-controlled switching mechanism delivers repeatable performance while the double-breaking contacts provide enhanced safety during fuse replacement and maintenance.
When used with a compatible Wöhner red/yellow rotary handle, the switch-disconnector can be employed as a mains isolator or Emergency OFF switch in accordance with IEC/EN 60204-1, making it well suited to modern industrial machinery and control panels.
