Why Choose the Wöhner 31260 SECUR CrossBoard Fuse Switch Disconnector?
The Wöhner 31260 is a compact, three-pole SECUR CrossBoard switch-disconnector-fuse designed for reliable circuit protection and load isolation in industrial control panels, machinery and low-voltage distribution equipment. It accepts D01 and D02 fuse links and mounts directly onto compatible Wöhner CrossBoard power distribution systems.
Rated at 35 A and 400 V AC, the Wöhner 31260 combines fuse protection with operator-independent switching through an integrated snap-action mechanism. This ensures that switching speed is not dependent on how quickly the operating handle is moved, supporting consistent and dependable circuit isolation.
The device features an LED indication for a blown fuse link, bottom outgoing connections and spring-clamp terminals for fast, tool-free conductor installation during initial assembly. Its narrow 22.5 mm width helps panel builders maximise available installation space while maintaining three-pole protection.

- Front protection rating of IP20.
Compact Fuse Protection and Safe Circuit Isolation
The Wöhner 31260 provides dependable protection for three-phase outgoing circuits by combining D0 fuse links with a load-break and isolating function. When fitted with correctly selected D01 or D02 fuse links, the device protects cables and connected equipment against overloads and short circuits while providing a clearly defined means of isolation.
Its operator-independent snap-action mechanism completes switching at a controlled speed, regardless of how the handle is operated. The integrated LED indication allows maintenance personnel to identify an operated fuse quickly, helping reduce fault-finding and equipment downtime.
Typical Applications
- Industrial control panels and switchboards.
- Machinery and production equipment.
- Motor and auxiliary circuit protection.
- Heating and ventilation control systems.
- OEM electrical distribution assemblies.
- CrossBoard 125 A, 250 A and 800 A installations.
