Why Choose the Mersen USFMCCMI UltraSafe Class CC Fuse Module?
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.

Advanced Motor Circuit Protection with Enhanced Safety
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.
