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.

Key Advantages

  • Reliable Class J time-delay fuse link for industrial circuit protection.
  • 25 A rated current suitable for machinery and feeder circuits.
  • 600 V AC and 400 V DC voltage ratings.
  • Time-delay characteristic accommodates temporary motor and transformer inrush currents.
  • High 200 kA AC short-circuit current rating.
  • Compact porcelain construction for dependable performance in industrial systems.

Key Features

  • Wöhner Class J fuse link manufactured by Mersen.
  • 25 A UL rated current.
  • 600 V AC rated voltage.
  • 400 V DC rated voltage.

  • Halogen-free porcelain construction.

Reliable Protection for Industrial Electrical Circuits

The Wöhner 31358 safely disconnects electrical circuits when sustained overloads or short-circuit currents exceed acceptable limits. Its high interrupting capacity helps reduce the risk of damage to cables, machinery, switchgear and other connected electrical equipment.

The time-delay operating characteristic makes this fuse particularly suitable for equipment that experiences elevated current during normal start-up. It supports reliable operation of motors, transformers and inductive loads while maintaining effective protection against genuine electrical faults.

Typical Applications

  • Industrial control panels and switchboards.
  • Motor and transformer protection circuits.
  • UL feeder circuits operating above 250 V.
  • Manufacturing and production machinery.
  • OEM electrical equipment.
  • Industrial power distribution systems.
