Overview

The Mersen Modulostar® CUS10 fuse holder (SKU: C1062717) provides reliable circuit protection for 10x38mm cylindrical fuse-links in industrial applications. Designed for DIN rail mounting per EN 60715, this 1-pole plus neutral (1+N) fuse holder supports both IEC and UL/CSA standards, with voltage ratings of 800VAC and 1000VDC. Constructed from durable thermoplastic or thermoset materials, the CUS10 series features flame-retardant properties with a glow wire flammability index up to 960°C, making it suitable for harsh environments including marine and railway applications. The modular design allows for field assembly of multi-pole units using pin-tie kits, while optional visual blown fuse indicators enhance maintenance efficiency. With a current rating of 32A and a short-circuit current rating (SCCR) of 200kA, this fuse holder is ideal for protecting motors, transformers, low-voltage distribution, control circuits, and drive systems up to 690V. Its compact form factor and DIN rail compatibility simplify integration into control panels and electrical enclosures.
  • 1-pole plus neutral (1+N) configuration for IEC and UL/CSA compliance
  • Supports 10x38mm cylindrical fuse-links with 800VAC/1000VDC ratings
  • IP20 finger-safe design for safe fuse replacement per IEC standards
  • 32A current rating with 200kA SCCR for robust circuit protection
  • Modular design enables field assembly of multi-pole units with pin-tie kits
