£135.64
The Mersen D301188 is an industrial electrical fuse intended for the protection of compatible power distribution, control and power electronic equipment. Manufactured by Mersen, a recognised specialist in electrical protection, it is suitable for maintenance, repair and replacement applications where the D301188 manufacturer reference is specified.
Industrial fuses are designed to interrupt excessive electrical current before damaging levels of heat and fault energy reach conductors, electronic components or connected machinery. When correctly selected and installed, the Mersen D301188 can support effective fault isolation, improved equipment reliability and reduced operational downtime.
Publicly indexed technical information for this exact reference is limited. The current rating, voltage rating, fuse class, breaking capacity, time-current characteristic, terminal arrangement and physical dimensions should therefore be verified from the product label, original component or official Mersen documentation before installation.
An industrial fuse opens the protected circuit when electrical current exceeds its defined operating limits. This helps reduce the risk of excessive heating, conductor damage and failure of connected electrical or electronic components during a fault.
Correct fuse selection is essential. The replacement must match the required current rating, voltage rating, utilisation category, operating speed, breaking capacity and mechanical format. The Mersen D301188 should only be installed where this exact reference or a formally approved equivalent is specified.

The Mersen D301188 is intended to provide electrical circuit protection within compatible industrial power, control and electronic equipment.
It may be used where the original component or equipment documentation specifies Mersen D301188. All electrical and mechanical characteristics must be checked before installation.
Verify the rated current, rated voltage, fuse class, breaking capacity, operating characteristic, terminal arrangement and physical dimensions.
It may be fitted within compatible industrial control panels, distribution assemblies, machinery and power electronic equipment.
An alternative should only be used when it is approved by the equipment manufacturer and matches every required electrical, performance and dimensional specification.
Mersen fuses are used by equipment manufacturers, electrical engineers and maintenance professionals to help protect critical industrial power and control systems.
