Why Choose the Wöhner 31324 Class J Fuse Link?
The Wöhner 31324 is a high-performance Class J fast-acting cylindrical fuse link designed to provide dependable overcurrent and short-circuit protection in industrial electrical systems. Manufactured by Mersen for the Wöhner product range, it is suitable for control panels, switchboards and machinery requiring reliable protection at voltages up to 600 V AC.
With a rated current of 15 A and a compact 21 × 57 mm Class J format, the Wöhner 31324 delivers rapid interruption of excessive current to help protect sensitive conductors, control equipment and electrical components. Its fast-acting characteristic responds quickly to fault conditions where intentional time delay is not required.
The fuse is rated for both 600 V AC and 300 V DC applications, with a short-circuit current rating of up to 200 kA AC. Its porcelain, halogen-free construction provides robust mechanical and thermal performance for demanding industrial environments.

Fast-Acting Protection for Industrial Circuits
Fast-acting Class J fuse links interrupt excessive current quickly, helping limit damage to conductors, control components and other electrical equipment during overload or short-circuit conditions. This makes the Wöhner 31324 particularly suitable for circuits that do not experience significant normal operating inrush currents.
Its high interrupting capacity supports installation in demanding industrial systems with substantial prospective fault currents. When installed in a compatible Class J fuse holder, the fuse provides compact and dependable circuit protection for machinery, automation equipment and electrical distribution assemblies.
