Why Choose the Mersen USGM3 UltraSafe™ Midget Fuse Holder?
The Mersen USGM3 is a compact and robust 3-pole Midget fuse holder designed to provide reliable overcurrent protection in industrial control panels, machinery and electrical distribution systems. As part of the advanced Mersen UltraSafe™ USGM series, it combines finger-safe construction with screwless spring pressure terminals for faster installation and dependable long-term operation.
Designed for 10 × 38 mm Midget fuses rated up to 30 A, the USGM3 supports circuits up to 750 V AC and 1000 V DC. Its three-pole configuration makes it particularly suitable for three-phase industrial systems where compact, coordinated fuse protection is required.
The USGM3 incorporates proven WAGO CAGE CLAMP® spring pressure terminal technology, providing secure, corrosion-resistant and vibration-resistant conductor connections without conventional terminal screws. Its DIN rail mounting arrangement and IP20 finger-safe protection make it an efficient solution for OEM machine builders, panel manufacturers and industrial maintenance engineers.

Reliable Three-Phase Circuit Protection
The Mersen USGM3 provides a secure mounting and connection point for three Midget fuses within one compact modular assembly. Each fuse protects its respective circuit pole by interrupting excessive current, helping safeguard wiring, control equipment, transformers and connected machinery against overload and short-circuit damage.
Its spring pressure terminal system maintains consistent contact force without requiring periodic terminal screw tightening. This reduces installation and maintenance requirements while providing dependable connections in applications exposed to vibration, temperature changes and demanding industrial operating conditions.
