Why Choose the Wöhner 31358 Class J Fuse Link?
The Wöhner 31358 is a high-performance Class J time-delay fuse link designed to provide dependable overload and short-circuit protection for industrial electrical installations. Manufactured by Mersen for Wöhner, this fuse is suitable for compatible Class J fuse holders, industrial switchgear and power distribution equipment.
The Wöhner 31358 combines a time-delay operating characteristic with a high short-circuit breaking capacity. This allows temporary starting currents from motors, transformers and other inductive loads to pass without unnecessary fuse operation, while sustained overloads and dangerous fault currents are safely interrupted.
With a rated current of 25 A, a 600 V AC supply rating and a compact 21 × 57 mm Class J format, the Wöhner 31358 is ideal for industrial machinery, feeder circuits, control panels and OEM electrical systems requiring reliable circuit protection.
