£5.53
The Wöhner 31374 is a high-performance cylindrical gG fuse link with striker, engineered to provide reliable overload and short-circuit protection for industrial electrical systems. Its compact 14 × 51 mm format makes it suitable for compatible fuse holders, switchgear assemblies and industrial control panels.
With a 40 A rated current and a 500 V AC rated voltage, the Wöhner 31374 provides full-range gG protection for cables, conductors and general-purpose electrical distribution circuits. The integrated striker pin provides mechanical indication when the fuse operates and can activate compatible monitoring, signalling or switching equipment, helping to reduce maintenance time and improve system availability.
Manufactured with a durable porcelain body and compliant with IEC 60269-1 and IEC 60269-2 (Fuse System F), the Wöhner 31374 is ideal for industrial machinery, control panels and electrical distribution systems where dependable circuit protection is essential.
The Wöhner 31374 protects cables, conductors and connected equipment by interrupting excessive current before damage can occur. Its gG characteristic provides comprehensive protection against both overloads and high short-circuit currents, supporting safe and reliable electrical installations.
The integrated striker pin enables rapid identification of a blown fuse and can activate compatible monitoring, signalling or switching devices. This simplifies maintenance, reduces troubleshooting time and helps minimise production downtime.
