Why Choose the Mersen USGCC3 UltraSafe Class CC Fuse Holder?
The Mersen USGCC3 is a compact and dependable three-pole UltraSafe™ Class CC fuse holder designed for industrial motor control, machinery and electrical distribution systems. It accommodates Class CC cartridge fuses rated up to 30 A, providing reliable overcurrent and short-circuit protection for three-phase circuits.
Part of the advanced Mersen UltraSafe USGCC series, the USGCC3 features proven WAGO CAGE CLAMP® screwless spring-pressure terminals. This connection technology reduces wiring time while maintaining secure conductor contact under vibration, thermal cycling and demanding industrial operating conditions.
Rated for 600 V AC and 600 V DC with a 200 kA short-circuit current rating, the USGCC3 combines IP20 finger-safe construction, clip-in fuse installation and standard DIN rail mounting. Its three-pole configuration makes it an effective solution for industrial control panels, OEM equipment and three-phase motor branch circuits.
