£78.22
The Wöhner 31264 is a compact three-pole SECUR CrossBoard switch-disconnector-fuse designed for reliable circuit protection and safe isolation using Class CC fuse links to UL 248-4. Designed for direct installation on CrossBoard 125 A, 250 A and 800 A systems, it combines fuse protection, load switching and isolation within a slim 22.5 mm housing for industrial control panels and OEM equipment.
Rated at 30 A and 600 V AC (UL), the device incorporates an operator-independent snap-action switching mechanism, ensuring reliable switching performance regardless of handle speed. An integrated LED blown-fuse indication enables maintenance engineers to identify a failed fuse quickly, reducing troubleshooting time.
The Wöhner 31264 features spring-clamp terminals for rapid tool-free installation during initial assembly together with bottom cable connections for tidy panel layouts. Its patented snap-on mounting system allows quick installation directly onto compatible CrossBoard busbar systems, making it ideal for modern industrial switchgear.
The Wöhner 31264 provides dependable overload and short-circuit protection using Class CC fuse links for three-phase outgoing circuits. Combining protection, switching and isolation within one compact device reduces installation space while improving panel safety and serviceability.
The integrated LED fuse indication enables rapid identification of blown fuses, while the operator-independent switching mechanism delivers consistent performance and the spring-clamp terminals minimise installation time during panel assembly.
