Why Choose the Mersen Q092819 High Voltage Motor Fuse Base?
The Mersen Q092819 is a robust DIN high voltage fuse base designed to provide secure mounting and dependable electrical connection for compatible motor protection fuse-links. Identified by the catalogue number SI130-45-442, it forms part of the Mersen range of fuse bases developed for high voltage motor fuse-links used in industrial switchgear and controlgear.
This single-pole fuse base is engineered for compatible high voltage fuse-links with a 45 mm diameter and a 442 mm body length. Its clip-mounted design enables straightforward fuse installation and replacement while maintaining the secure contact pressure and mechanical stability required for demanding medium voltage applications.
With a rated operating voltage of 7.2 kV AC and a maximum rated current of 400 A, the Q092819 is suitable for indoor motor starters, switchgear assemblies and industrial power distribution equipment. It can also support a compatible indicating device that uses the striker of an operated fuse-link to activate a microswitch, alarm or circuit-opening mechanism.
