Overview

Mersen Modulostar CUS10 fuse holders (SKU: E1062719) are compact, DIN rail-mounted devices designed for 10.3x38.1mm cylindrical fuse-links. These 1-pole + neutral (1+N) fuse holders deliver reliable overcurrent protection in industrial power distribution and control circuits with ratings up to 800VAC and 1000VDC at 32A continuous current. The CUS10 series features a standard visual indicator for immediate blown fuse detection, eliminating the need for manual inspection and reducing system downtime. Available in 1, 2, 3, or 4-pole configurations with or without indicators, these fuse holders support flexible system design. The 1+N variant (CUS101NI) includes a dedicated neutral conductor terminal for balanced load distribution in single-phase applications. Constructed from durable thermoplastic or thermoset materials, the CUS10 series withstands harsh industrial environments while maintaining finger-safe operation per IEC standards. Installation is simplified via standard EN 60715 DIN rail mounting, enabling quick integration into control panels and electrical enclosures. The IP20 ingress protection rating ensures basic protection against solid foreign objects while allowing for ventilation. With a maximum power dissipation of 3W per fuse link and conventional free-air thermal current rating of 32A, these fuse holders are engineered for high-reliability applications including motor control centers, power supplies, and industrial machinery. Pin-tie assembly kits are available for multi-pole field configurations.
