Why Choose the Mersen USGM1I UltraSafe™ Midget Fuse Holder?
The Mersen USGM1I is a compact and reliable single-pole Midget fuse holder designed for safe circuit protection in industrial control panels, machinery and electrical distribution systems. As part of the advanced Mersen UltraSafe™ USGM series, it combines finger-safe protection with screwless spring pressure terminal technology for efficient installation and dependable long-term performance.
This fuse holder is suitable for Midget fuses rated up to 30 A and can be used on both 600 V AC and 600 V DC circuits. An integrated LED indication system provides a clear visual warning when the installed fuse has operated, helping maintenance teams identify faults quickly and reduce equipment downtime.
The USGM1I features proven CAGE CLAMP® spring pressure connections, allowing solid or stranded conductors to be terminated without conventional terminal screws. Its slim polyamide housing, DIN rail mounting arrangement and IP20 finger-safe design make it particularly suitable for space-conscious industrial panel building and automation applications.

Reliable Fuse Protection for Industrial Control Systems
Fuse holders such as the Mersen USGM1I provide a secure and accessible mounting point for replaceable Midget fuses. When excessive current or a short circuit occurs, the installed fuse interrupts the circuit to help protect wiring, components and connected industrial equipment from damage.
The integrated LED indication system allows maintenance engineers to identify an operated fuse without lengthy circuit tracing. Combined with finger-safe construction and maintenance-free spring terminals, the USGM1I supports safer, faster and more efficient control panel installation and servicing.
