Why Choose the Mersen Q075569 High Voltage Motor Fuse Base?
The Mersen Q075569 is a robust DIN high voltage fuse base designed to provide secure mounting and reliable electrical connection for compatible motor protection fuse-links. Identified by the catalogue number SI175-45-442, it forms part of the Mersen range of fuse bases developed specifically for high voltage motor fuse-links used in industrial switchgear and controlgear.
This single-pole fuse base is engineered for compatible fuse-links with a 45 mm diameter and a 442 mm body length. Its clip-mounted design allows 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 12 kV AC and a maximum rated current of 250 A, the Q075569 is suitable for indoor motor starters, switchgear assemblies and industrial power distribution equipment. It can also support a compatible indication device that uses the fuse-link striker to activate a microswitch, alarm or circuit-opening mechanism.
