The Wöhner 31355 is a dependable Class J time-delay fuse link designed to protect industrial electrical circuits against overloads and short circuits. Manufactured by Mersen for Wöhner, it is suitable for compatible fuse holders, switchgear and power distribution systems requiring reliable protection at high operating voltages.
This industrial fuse link combines a time-delay operating characteristic with a high short-circuit breaking capacity. The delayed response allows brief motor-starting and transformer inrush currents to pass without unnecessary fuse operation, while sustained overloads and dangerous fault currents are safely interrupted.
With a rated current of 15 A, a 600 V AC rating and a compact 21 × 57 mm Class J format, the Wöhner 31355 is ideal for industrial control panels, motor circuits, machinery and feeder circuits operating above 250 V.
The Wöhner 31355 disconnects a circuit when sustained overloads or high fault currents exceed safe operating limits. Its high interrupting capacity helps contain severe short circuits, reducing the risk of damage to cables, switchgear and connected industrial equipment.
The time-delay characteristic makes this fuse particularly suitable for circuits containing motors, transformers and other inductive equipment. These loads can draw temporarily elevated current during start-up, which the fuse can tolerate without compromising protection against genuine fault conditions.
