Overview

Mersen USCC3 UltraSafe™ 3-pole fuse holder (SKU: USCC3) delivers industry-leading safety for Class CC fuses up to 30A at 600VAC/DC. Engineered for high-performance industrial applications, this UL-listed holder meets IEC and DIN finger-safe standards (IP20) during fuse replacement, eliminating exposure to live components. The compact polyamide housing resists impact and provides exceptional insulation, while the tool-free, snap-on DIN-rail mounting (35mm) reduces panel assembly time by up to 15% compared to traditional solutions. Designed for motors, control circuits, transformers, and photovoltaic systems, the USCC3 supports Type "2" No Damage protection when paired with compatible Class CC fuses (ATDR, ATMR, ATQR). The 3-pole configuration enables balanced load distribution, and optional visual blown-fuse indicators (90VAC/115VDC minimum) provide immediate fault detection with <0.7mA leakage at 600V. SCCR ratings of 200kA ensure robust short-circuit protection across AC/DC applications. Multi-pole units can be field-assembled using pin-tie handles for flexible configurations.
