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.
