Mersen USFMCCMI UltraSafe three-pole Class CC fuse module with integrated LED blown-fuse indication and microswitch auxiliary contact, rated 30 A and 600 V AC/DC.
£140.67
The Mersen USFMCCMI is a premium UltraSafe™ three-pole Class CC fuse module with integrated LED indication and microswitch auxiliary contact, designed to provide dependable overcurrent protection for industrial motor control, machinery and automation systems. It accommodates Class CC cartridge fuses rated up to 30 A while combining advanced safety features with a compact footprint.
As part of the Mersen UltraSafe USFM Series, the USFMCCMI incorporates both LED blown-fuse indication for rapid fault identification and an integrated microswitch auxiliary contact. When correctly wired to an adjacent IEC contactor, the microswitch causes the contactor to drop out before the fuse extractor handle opens, helping prevent opening the fuse module under load and improving maintenance safety.
Rated for 600 V AC and 600 V DC, the USFMCCMI features pressure plate terminals, IP20 finger-safe construction, padlocking capability and tool-free DIN rail removal. Its compact 45 mm-wide design coordinates perfectly with IEC contactors and overload relays, making it ideal for modern industrial control panels.
The Mersen USFMCCMI securely houses three Class CC cartridge fuses while combining visual blown-fuse indication with an integrated microswitch auxiliary contact. This combination allows maintenance engineers to identify an open fuse quickly while ensuring the connected contactor disconnects the load before the fuse module is opened.
Its compact 45 mm footprint, finger-safe construction, pressure plate terminals and DIN rail mounting make the USFMCCMI an excellent choice for OEM machinery, industrial automation, motor control centres and electrical distribution panels where both safety and maintenance efficiency are priorities.

The USFMCCMI provides overcurrent protection for three-phase industrial circuits using Class CC fuses while incorporating LED indication and an integrated microswitch for enhanced operational safety.
The microswitch can be wired to an adjacent contactor so that the load is disconnected before the fuse extractor handle is opened, improving maintenance safety.
The integrated LED provides clear visual identification of an open fuse, reducing fault-finding time and simplifying maintenance.
The module is rated for systems up to 600 V AC and 600 V DC.
The module mounts directly onto a standard DIN rail and includes tool-free removal together with pressure plate terminals for efficient installation.
Mersen UltraSafe™ fuse modules are trusted by OEMs, panel builders and industrial maintenance engineers for delivering compact, finger-safe circuit protection with advanced safety features and simplified fault diagnosis.
