The Mersen P330155 is an industrial electrical protection fuse designed to safeguard compatible circuits and equipment against damaging overcurrent and short-circuit conditions. Manufactured by Mersen, it is suitable for maintenance, repair and replacement applications where dependable circuit interruption is essential.
The fuse operates by disconnecting the protected circuit when current exceeds its specified operating limits. This helps reduce the risk of damage to electrical components, conductors and connected machinery while supporting safer and more reliable system performance.
The Mersen P330155 fuse-link is intended for installation in a compatible and correctly rated fuse holder or mounting assembly. Before fitting the fuse, its current rating, voltage rating, operating class, breaking capacity, dimensions and connection arrangement should be checked against the original equipment documentation.

Reliable Protection for Industrial Electrical Equipment
Industrial fuse-links provide essential protection by interrupting excessive current before it causes extensive damage to equipment or conductors. Once the fuse element operates, the affected circuit is isolated and the fuse must be replaced with a correctly specified equivalent.
Correct fuse selection is critical. A replacement must match the required current and voltage ratings, utilisation category, breaking capacity, time-current characteristic and physical configuration specified by the equipment manufacturer.
Typical Applications
Industrial machinery and production equipment.
Electrical control and distribution panels.
Motor-control and automation systems.
Power-control and conversion equipment.
Maintenance and replacement fuse applications.
