£69.06
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.
The Mersen USFM10 provides a secure mounting and connection point for three midget fuses used to protect industrial conductors, contactors, overload relays and connected machinery. Its compact 45 mm width enables it to align with similarly sized IEC motor-control components, producing an organised and space-efficient assembly.
Integrated fuse extraction handles simplify access during maintenance, while the finger-safe housing helps protect personnel from accidental contact. The module's DIN rail adapter also enables quick installation and removal, making the USFM10 particularly suitable for OEM equipment and densely populated control cabinets.
