The Wöhner 31968 is a three-pole Class J busbar mounted fuse holder with integrated LED indication, supplied as a complete solution on a busbar adapter for the Wöhner AMBUS® 60Classic system. Designed for Class J fuse links (1–30 A, 21 × 57 mm), it delivers reliable branch circuit protection for industrial control panels, machinery and power distribution systems while providing rapid visual identification of an operated fuse.
The integrated LED indication allows maintenance engineers to quickly identify a blown fuse, reducing troubleshooting time and helping minimise machine downtime. Its direct mounting onto compatible 60 mm busbar systems creates a compact, organised installation with significantly reduced wiring compared to conventional fuse holder arrangements.
Rated at 30 A with a 600 V operating voltage, the Wöhner 31968 is ideal for protecting industrial control circuits, motor control panels, OEM machinery and electrical distribution equipment requiring UL Class J fuse protection.
The Wöhner 31968 combines high-performance Class J fuse protection with integrated visual fuse monitoring in one compact assembly. By mounting directly onto the Wöhner 60Classic busbar system, it simplifies panel construction while improving serviceability and reducing installation time.
