Why Choose the Mersen N300139 Industrial Fuse?
The Mersen N300139 is an industrial electrical fuse designed to help protect compatible circuits and equipment against potentially damaging overcurrent and short-circuit conditions. Manufactured by Mersen, a recognised specialist in electrical power protection, this component is suitable for professional maintenance, repair and replacement applications.
When electrical current rises beyond the permitted operating level, the Mersen N300139 provides a controlled interruption point within the circuit. This helps limit damage to cables, control components, power electronics and connected industrial equipment while reducing the risk of a localised electrical fault affecting a wider system.
The N300139 fuse is intended for installation within a compatible fuse holder, switchgear assembly or industrial circuit protection system. Before ordering or installation, its rated current, rated voltage, utilisation category, breaking capacity, terminal arrangement and physical dimensions should be verified against the original component and the equipment manufacturer’s documentation.

Reliable Protection for Industrial Electrical Systems
Industrial fuses form an essential part of an electrical protection strategy. When excessive current passes through a correctly selected fuse, its internal element operates and disconnects the affected circuit, helping protect wiring, equipment and surrounding components against further electrical and thermal damage.
Replacement fuses must match the electrical characteristics and physical configuration specified by the equipment manufacturer. The Mersen N300139 reference, rated current, voltage, utilisation category, breaking capacity and terminal format should therefore be checked carefully before the circuit is energised.
