Why Choose the Wöhner 33513 QUADRON® 60Classic Speed Fuse Switch-Disconnector?
The Wöhner 33513 is a premium three-pole NH size 1 fuse switch-disconnector engineered for dependable switching, isolation and overcurrent protection in industrial low-voltage power distribution systems. As part of the QUADRON® 60Classic Speed range, it features a bottom M10 cable connection and is designed for operation via a front door coupling rotary handle, allowing safe switching from outside the enclosure while maintaining maximum operator protection.
The switch incorporates an operator-independent snap-action mechanism with double-breaking main contacts, ensuring fast and reliable switching regardless of handle speed. The design also allows safe, tool-free fuse replacement while providing an additional visible isolation gap when the cover and fuse assembly are removed.
Designed for NH size 1 fuse links, the Wöhner 33513 is rated at 250 A and mounts directly onto compatible 60Classic busbar systems using Wöhner's proven CrossLink® adapter technology. It is suitable for use as both a mains isolator and, when fitted with the appropriate red/yellow rotary handle, an Emergency OFF switch in accordance with IEC/EN 60204-1.
