The Mersen USGM3I is a premium 3-pole Midget fuse holder with integrated LED indication from the UltraSafe™ USGM series, engineered to provide dependable overcurrent protection in industrial control panels, power distribution equipment and automation systems. Designed for 10 × 38 mm Midget fuses up to 30 A, it combines advanced safety features with maintenance-free spring pressure terminal technology for fast installation and reliable long-term performance.
The integrated LED blown fuse indication provides immediate visual identification of an operated fuse, allowing maintenance personnel to quickly locate faults and minimise machine downtime. Its compact DIN rail mounted construction and IP20 finger-safe design make it ideal for modern industrial electrical panels.
Featuring industry-proven WAGO CAGE CLAMP® spring pressure terminals, the USGM3I delivers secure, vibration-resistant electrical connections without terminal screws, reducing installation time while providing maintenance-free operation throughout the product's service life.
The Mersen USGM3I has been developed to improve both installation efficiency and maintenance within modern industrial control panels. The spring pressure terminal technology eliminates terminal screw tightening while providing secure, corrosion-resistant and vibration-proof electrical connections for demanding industrial environments.
Its integrated LED indication provides immediate visual confirmation when a fuse has operated, allowing maintenance engineers to identify faults quickly and restore equipment with minimal downtime. The compact modular design is ideal for automation systems, machinery and power distribution applications.
