Overview
The Mersen USCC1 Class CC UltraSafe fuse holder is a modular, single-pole fuseholder designed for Class CC and midget fuses up to 30 amperes. It qualifies as “fingersafe” under IEC and DIN standards to an IP20 grade of protection, including fuse changing (with the flick of a finger). This holder provides Type “2” no-damage protection—one of the safest fuse protection packages in industrial control and electrical distribution applications.
Key Features
- Tough and durable polyamide body with exceptional insulating properties
- Finger-safe design with IP20 protection rating under IEC and DIN standards
- Saves up to 15% mounting space and snaps onto 35mm DIN rail for faster panel assembly
- Single-pole, no-indicator configuration for clean panel layouts
- Supports Class CC and 1-1/2″ x 13/32″ midget fuses
- Field-expandable: multiple units can be stacked and secured with pin-tie handles

Typical Applications
The USCC1 is commonly used in industrial control cabinets, motor starter panels, PLC input/output circuits, and process automation equipment. It provides arc-free fuse protection in crowded panel environments where space savings and worker safety are priorities. Typical installations include machine tool controls, HVAC panels, and packaged equipment protection circuits.
