Why Choose the Wöhner 31333 Class J Fuse Link?
The Wöhner 31333 is a dependable Class J time-delay cylindrical fuse link designed to protect industrial electrical circuits against overloads and short circuits. Manufactured by Mersen for the Wöhner product range, it combines reliable fault protection with the ability to tolerate temporary current surges during normal equipment start-up.
Rated at 1 A, the Wöhner 31333 supports operating voltages up to 600 V AC and 500 V DC. Its time-delay characteristic helps prevent nuisance operation during brief inrush conditions while still providing effective protection against sustained overloads and damaging fault currents.
The compact 21 × 57 mm Class J format allows the fuse link to be installed in compatible Class J fuse holders within control panels, switchboards and OEM machinery. Supplied in packs of ten, it is a practical protection solution for industrial automation, control and power distribution applications.
