Why Choose the Mersen USGCC3IN UltraSafe Class CC Fuse Holder?
The Mersen USGCC3IN is a compact UltraSafe™ Class CC fuse holder with three fused poles, a neutral pole and integrated blown-fuse indication. Designed for industrial control panels, machinery and power distribution equipment, it accommodates Class CC cartridge fuses rated up to 30 A while providing a coordinated three-phase plus neutral arrangement.
Part of the advanced Mersen UltraSafe USGCC series, the USGCC3IN uses proven WAGO CAGE CLAMP® screwless spring-pressure terminals. This connection technology reduces wiring time, maintains consistent conductor contact pressure and provides dependable resistance to vibration, corrosion and temperature cycling without routine terminal retightening.
Rated for applications up to 600 V AC and 600 V DC, the USGCC3IN combines LED fuse-status indication, IP20 finger-safe construction and standard DIN rail mounting. Its three-pole plus neutral configuration makes it particularly suitable for three-phase systems that require a matching neutral connection within one organised modular assembly.

Three-Phase Protection with an Integrated Neutral Connection
The Mersen USGCC3IN provides three Class CC fuse positions together with a matching neutral pole, allowing panel builders to create a compact and consistent three-phase plus neutral assembly. The neutral section provides a dedicated conductor connection and does not require a fuse.
Integrated fuse-status indication helps maintenance teams identify an operated fuse quickly, while the WAGO CAGE CLAMP® terminals simplify conductor installation and maintain reliable contact pressure throughout the holder's service life. These features make the USGCC3IN well suited to industrial systems where safety, fast maintenance and efficient panel wiring are priorities.
Typical Applications
- Three-phase plus neutral industrial control panels.
- Motor-control and machinery circuits.
- Industrial automation systems.
- OEM production equipment.
- Power distribution and control cabinets.
- Control transformers and power supplies.
- Manufacturing and processing machinery.
- Panels requiring visual fuse-status indication.
