£661.21
The Wöhner 33515 is a premium three-pole NH size 1 fuse switch-disconnector engineered for dependable switching, safe isolation and overcurrent protection in industrial low-voltage power distribution systems. Part of the QUADRON® Panel Speed range, it is designed for mounting plate installation and operation via a door coupling rotary handle, allowing safe external switching without opening the enclosure.
The switch incorporates an operator-independent snap-action switching mechanism with double-breaking main contacts, ensuring fast, consistent switching performance regardless of handle speed. The double-breaking design enables safe, tool-free fuse replacement while providing an additional visible isolation gap when the cover and fuse carriers are removed.
Designed for NH size 1 fuse links, the Wöhner 33515 has a 250 A rated current and operates at up to 690 V AC. Its robust M10 screw terminals provide secure cable termination, making it an excellent solution for industrial switchboards, OEM machinery, motor control centres and main power distribution panels.
The Wöhner 33515 enables operators to switch and isolate power safely from outside the enclosure using a compatible rotary handle and extension shaft. The spring-controlled switching mechanism delivers reliable performance during frequent switching operations, while the FLAG position indicator provides a clear visual indication of the switch status.
The unit can be used as a mains disconnector in accordance with IEC/EN 60204-1 and, when fitted with the appropriate red/yellow rotary handle, also functions as an Emergency OFF switch. The handle can be padlocked in the OFF position to improve maintenance safety and prevent unauthorised operation.
