Why Choose the Wöhner 31299 Class CC Fuse Holder with LED?
The Wöhner 31299 is a high-performance 2-pole Class CC fuse holder with integrated LED indication, designed to provide dependable circuit protection and rapid identification of operated fuse links. Part of the established Wöhner AMBUS® Panel range, it is suitable for industrial control panels, OEM machinery and electrical distribution equipment requiring a compact UL and CSA approved fuse-holding solution.
The integrated indicator light signals when a fuse link has tripped, provided the closed fuse holder remains energised. This allows maintenance personnel to locate affected circuits more quickly, reducing troubleshooting time and helping minimise equipment downtime. The indicator is suitable for 110–600 V AC/DC systems and can be used with either DC polarity.
Rated at 30 A and 600 V AC/DC, the Wöhner 31299 accepts Class CC fuse links manufactured in accordance with UL 248-4. Its two-pole construction, DIN rail mounting and large cage clamp terminals make it a practical choice for single-phase circuits, control transformers, motor circuits and industrial automation systems.

Fast Fault Detection with Integrated LED Indication
The Wöhner 31299 combines Class CC fuse protection with a built-in indicator that helps engineers identify a tripped fuse without immediately removing the fuse link. When the holder is closed and the circuit is energised, the LED illuminates after the installed fuse has operated.
Its two-pole design is particularly suitable for single-phase and two-conductor circuits. The compact housing occupies only two modular spaces, while the large terminal capacity provides flexibility when connecting stranded, solid or ferruled copper conductors.
Typical Applications
- Industrial control panels.
- Single-phase machinery circuits.
- Motor control and protection systems.
- Control transformers and power supplies.
- Industrial automation equipment.
- Feeder and branch-circuit protection.
- Equipment built to UL and CSA standards.
