Why Choose the Mersen T301064 Industrial Fuse?
The Mersen T301064 is an industrial electrical fuse intended to provide dependable overcurrent and short-circuit protection in compatible power, control and automation equipment. Manufactured by Mersen, this replacement component is suitable for electrical systems in which the exact T301064 manufacturer reference has been specified.
A correctly selected fuse protects an electrical circuit by interrupting excessive current before damaging levels of heat and electrical stress can affect conductors, switching devices or connected equipment. Its passive operating principle requires no auxiliary power, control signal or manual activation during a fault condition.
The Mersen T301064 is suitable for industrial maintenance, repair and OEM replacement requirements. Its rated current, voltage, utilisation category, breaking capacity, physical dimensions and terminal arrangement should be checked against the original fuse, equipment documentation or an authorised Mersen data source before installation.

Reliable Protection for Industrial Electrical Systems
Overcurrents and short circuits can expose electrical equipment to excessive heat, high electromagnetic forces and potentially damaging fault energy. A correctly specified fuse responds by opening the affected circuit, helping prevent the fault from causing further damage to downstream components.
Correct fuse selection is essential for dependable system protection. Any replacement must satisfy the required current rating, voltage rating, operating characteristic, breaking capacity, physical size and connection arrangement. The T301064 should only be installed where this exact part number or a formally approved equivalent has been specified.
Typical Applications
- Industrial electrical control panels.
- Power distribution and conversion equipment.
- Motor control and automation systems.
- Manufacturing and processing machinery.
- OEM electrical assemblies.
- Replacement of an existing Mersen T301064 fuse.
