The Mersen N300116 is an industrial electrical fuse designed to help protect compatible circuits and equipment against 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 current rises beyond the permitted operating level, the Mersen N300116 provides a controlled interruption point within the electrical circuit. This helps limit damage to cables, control components, power electronics and connected industrial equipment while reducing the possibility of a localised fault affecting a wider system.
The N300116 fuse is intended for installation in a compatible fuse holder, switchgear assembly or industrial protection system. Before ordering or fitting the component, its rated current, voltage, utilisation category, breaking capacity, terminal arrangement and physical dimensions should be verified against the original fuse and the equipment manufacturer’s documentation.
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 N300116 reference, rated current, voltage, utilisation category, breaking capacity and terminal format should therefore be checked carefully before the circuit is energised.

The Mersen N300116 is used to protect compatible industrial electrical circuits and equipment against excessive current and short-circuit faults.
Yes. It can be used where Mersen N300116 is the specified reference, provided its electrical ratings, fuse class, dimensions and terminal configuration match the original component.
Compare the manufacturer reference, rated current, rated voltage, utilisation category, breaking capacity, dimensions and terminal format with the original fuse and the equipment manufacturer’s documentation.
The correct fuse rating ensures that the circuit receives its intended level of protection. An unsuitable fuse may operate unnecessarily or fail to interrupt a dangerous electrical fault quickly enough.
The fuse should be selected and installed by a suitably qualified electrical professional in accordance with the equipment instructions and applicable electrical safety requirements.
Mersen electrical protection products are used by engineers, equipment manufacturers and maintenance professionals to support dependable fault protection in industrial power, control and automation systems.
