31252 Wohner cylindr. fuse link 30 A

Why Choose the Wöhner 31252 Class CC Fuse Link?

The Wöhner 31252 is a compact and dependable Class CC time-delay cylindrical fuse link designed to protect control transformers and industrial electrical circuits against overloads and short circuits. Manufactured by Mersen for Wöhner, it provides reliable circuit protection for control panels, switchgear, automation equipment and OEM machinery.

The time-delay operating characteristic allows the fuse to tolerate temporary inrush currents generated when transformers and inductive equipment are energised. This helps prevent unnecessary fuse operation while maintaining effective protection against sustained overcurrent conditions and electrical faults.

With a rated current of 30 A, a 600 V AC rating and a high 200 kA AC short-circuit current rating, the Wöhner 31252 is suitable for demanding industrial installations. Its compact Class CC format, porcelain construction and halogen-free materials support safe and reliable operation where panel space is limited.

Reliable Protection for Industrial Electrical Systems

Class CC fuse links protect electrical equipment by interrupting excessive current caused by overloads and short circuits. Their compact, rejection-style format enables high-performance circuit protection to be installed in compatible Class CC fuse holders while helping prevent the use of incorrectly rated fuse types.

The time-delay characteristic of the Wöhner 31252 allows normal temporary current surges to pass without unnecessary interruption. This makes it particularly suitable for control transformers and other industrial loads that can draw elevated current during energisation.

Typical Applications

• Industrial control transformer protection.
• Electrical control panels and cabinets.
• Factory automation equipment.
• Industrial machinery and production systems.
• OEM machine-building applications.
• Switchgear and electrical distribution assemblies.
