£422.93
The Mersen S1005553 is a dependable high voltage fuse-link designed to protect transformers, switchgear and medium voltage electrical distribution equipment against damaging fault currents. Identified by the Mersen catalogue reference TP360V6,3A325M3, this fuse combines a 36 kV rated voltage with a 6.3 A current rating.
Engineered for use in demanding power distribution installations, the S1005553 helps interrupt electrical faults before excessive thermal and mechanical energy can damage valuable equipment. Its robust cylindrical construction supports reliable performance within compatible medium voltage fuse holders and switchgear assemblies.
The fuse incorporates an M3 striker mechanism, enabling it to interact with compatible switch-disconnector or tripping equipment when the fuse operates. Its approximately 325 mm fuse-link format makes it suitable for specifically matched medium voltage installations where dependable transformer protection and coordinated switchgear operation are required.
High voltage fuse-links protect transformers and distribution equipment by interrupting excessive fault currents before they can cause severe thermal or mechanical damage. Rapid fault clearance helps improve installation safety, preserve equipment and reduce the risk of extended system downtime.
The Mersen S1005553 is intended for use as part of a correctly coordinated medium voltage protection system. Its striker mechanism can provide mechanical indication or initiate operation of compatible switchgear when the fuse has interrupted a fault.
