Why Choose the Mersen M25F30S Fuse Switch Disconnector?
The Mersen M25F30S is a compact 25 A fuse switch disconnector designed to provide reliable switching, electrical isolation and fuse protection within low-voltage industrial control systems. Developed for use with FR10 cylindrical fuse links, it combines manual circuit disconnection with replaceable overcurrent protection in one practical assembly.
Featuring a three-pole 3+0 configuration and a right-hand side-operated mechanism, the M25F30S is particularly suited to electrical panels and machinery enclosures where side operation is required. All three phase conductors can be disconnected simultaneously, creating a clearly defined isolation point for maintenance and servicing.
With a rated current of 25 A, the M25F30S is suitable for smaller machinery, control circuits, auxiliary supplies and industrial distribution applications. When fitted with correctly selected FR10 fuse links, it helps protect cables and connected equipment against overload and short-circuit conditions.

Compact Switching and Fuse Protection
Fuse switch disconnectors combine a mechanical isolation device with replaceable fuse links. The Mersen M25F30S allows three-phase circuits to be manually disconnected while the installed FR10 fuses provide protection against excessive current and short-circuit faults.
Its side-operated arrangement is useful in customised control panels where front access is restricted or where the operating control must be positioned on the side of the enclosure. Fuse links should be selected according to the load characteristics, conductor size and required protection performance.
Typical Applications
- Industrial control panels.
- OEM machinery and production equipment.
- Three-phase auxiliary circuits.
- Motor and equipment protection.
- Industrial automation systems.
- Commercial electrical distribution assemblies.
