The Wöhner 31359 is a premium Class J time-delay fuse link designed to provide dependable overload and short-circuit protection for industrial electrical systems. Manufactured by Mersen for Wöhner, it is engineered for use with compatible Class J fuse holders, switchgear and busbar systems, ensuring reliable protection for industrial machinery and power distribution equipment.
Designed to meet UL 248-8 and UL 248-1 standards, the Wöhner 31359 features a time-delay operating characteristic that allows temporary motor starting and transformer inrush currents without unnecessary fuse operation. This helps maximise equipment uptime while maintaining excellent protection against sustained overloads and fault currents.
With a 30 A current rating, a 600 V AC operating voltage and a compact 21 × 57 mm Class J format, the Wöhner 31359 is ideal for industrial control panels, OEM machinery, feeder circuits and electrical distribution systems requiring dependable circuit protection.
The Wöhner 31359 safely disconnects electrical circuits when overloads or short-circuit currents exceed acceptable operating limits. Its high interrupting capacity helps minimise the risk of damage to switchgear, cables and connected industrial equipment while improving overall system reliability.
The time-delay characteristic makes this fuse particularly suitable for circuits supplying motors, transformers and other inductive loads. It allows temporary inrush currents during start-up while maintaining effective protection against sustained overloads and electrical faults.
