The Mersen N301335 is an industrial fuse-link designed to provide dependable electrical protection for compatible power-control, automation and machinery applications. Manufactured by Mersen, a recognised specialist in circuit protection, this fuse helps protect cables, components and connected equipment against potentially damaging overcurrent and short-circuit conditions.
Industrial fuse-links operate by interrupting excessive fault current before it can cause extensive damage to electrical equipment. The Mersen N301335 is suitable for maintenance, replacement and original equipment applications where reliable circuit protection is required to support operational safety and minimise unplanned downtime.
Before installing the N301335, its rated current, rated voltage, utilisation category, breaking capacity, dimensions and terminal configuration should be verified from the markings on the fuse or current official Mersen documentation. Correct specification matching is essential because fuse-links with a similar appearance may have significantly different electrical characteristics.
Industrial fuse-links protect electrical systems by opening the circuit when current exceeds their specified operating limits. A correctly selected fuse can restrict fault energy, protect downstream components and reduce the risk of extensive damage to machinery, control panels and power-distribution equipment.
When replacing the Mersen N301335, engineers should verify the complete product reference together with the current rating, voltage rating, utilisation category, breaking capacity, dimensions and terminal arrangement. Selecting a replacement solely by physical appearance is not recommended because visually similar fuse-links may provide substantially different protection characteristics.

The Mersen N301335 is used to provide overcurrent and short-circuit protection within compatible industrial electrical equipment, control systems and power assemblies.
Check the rated current, rated voltage, utilisation category and breaking capacity printed on the fuse-link or listed in current official Mersen technical documentation.
A substitute should only be installed when its current rating, voltage rating, utilisation category, breaking capacity, dimensions and terminal arrangement match the original specification.
It may be installed in a compatible fuse holder, control panel, switchgear assembly or industrial equipment enclosure, subject to the equipment manufacturer's requirements.
The fuse should be installed by a suitably qualified electrical professional after the equipment has been safely isolated and all required specifications have been verified.
Mersen electrical protection products are used by industrial engineers, equipment manufacturers and maintenance professionals to support reliable operation across power distribution, machinery and automation applications.
