Why Choose the Mersen USFMCCI UltraSafe Class CC Fuse Module?
The Mersen USFMCCI is a compact UltraSafe™ three-pole Class CC fuse module with LED indication, designed to provide reliable overcurrent protection for industrial motor control, machinery and automation systems. It accepts Class CC cartridge fuses rated up to 30 A, making it a practical solution for protecting three-phase branch circuits and associated electrical equipment.
Part of the Mersen UltraSafe USFM series, the USFMCCI features visual fuse-status indication to help maintenance personnel identify an open fuse quickly. This can reduce fault-finding time, simplify maintenance and help restore industrial equipment to service more efficiently following an overcurrent event.
Rated for applications up to 600 V AC and 600 V DC, the USFMCCI combines pressure-plate terminals, IP20 finger-safe construction and convenient DIN rail mounting. Its compact 45 mm-wide format is designed to coordinate neatly with IEC contactors and overload relays in space-conscious motor-control panels.
