Why Choose the Wöhner 31243 Class CC Fast-Acting Fuse?
The Wöhner 31243 is a high-performance 30 A Class CC fast-acting cylindrical fuse link designed for dependable branch-circuit protection in industrial control panels, machinery and electrical distribution equipment. Supplied by Wöhner and manufactured by Eaton, this compact fuse provides rapid interruption of overload and short-circuit currents to help protect cables, components and connected equipment.
Rated at 600 V AC, the Wöhner 31243 is manufactured in accordance with UL 248-1 and UL 248-4. It provides a high 200 kA short-circuit current rating, making it suitable for installations where substantial prospective fault currents may be present.
The fuse features a durable porcelain body, halogen-free construction and compact 10 × 38 mm dimensions. Its fast-acting characteristic makes it particularly suitable for branch circuits and equipment that require rapid fault clearance without an intentional time delay.

Fast-Acting Protection for Industrial Branch Circuits
The Wöhner 31243 protects branch circuits by rapidly interrupting excessive current before it can cause significant damage to conductors, control equipment or connected electrical components. Unlike time-delay fuse links, its fast-acting characteristic provides prompt operation when a qualifying overload or short circuit occurs.
Its Class CC rejection-style format helps ensure installation in compatible Class CC fuse holders. Combined with a 600 V AC rating and 200 kA SCCR, the fuse is well suited to industrial control systems, machine-building applications and commercial electrical equipment requiring compact, high-performance overcurrent protection.
