Why Choose the Mersen USFM10 UltraSafe Fuse Module?
The Mersen USFM10 is a compact three-pole UltraSafe™ fuse module designed for reliable overcurrent protection in industrial motor control, machinery and automation systems. It accepts 10 × 38 mm midget fuses rated up to 30 A, providing a practical solution for protecting three-phase circuits within electrical control panels.
Part of the Mersen UltraSafe USFM range, this fuse module has a space-saving 45 mm-wide design that aligns neatly with commonly used IEC contactors and overload relays. Its coordinated format helps panel builders produce compact motor-control assemblies while simplifying component placement, wiring and maintenance.
Rated for applications up to 600 V AC and 600 V DC, the USFM10 incorporates pressure-plate terminals, IP20 finger-safe protection and convenient DIN rail mounting. Easy-operating fuse extraction handles and provision for padlocking further support safe inspection and fuse replacement in demanding industrial installations.
