Why Choose the Mersen A1062715 CUS103 Modulostar Fuse Holder?
The Mersen A1062715, also designated CUS103, is a compact three-pole DIN rail fuse holder designed for reliable circuit protection in industrial electrical installations. Part of the Mersen Modulostar CUS10 series, it accommodates cylindrical fuse links measuring 10 × 38 mm and supports both IEC and UL/CSA applications.
This fuse holder combines a space-saving modular construction with finger-safe operation to an IP20 protection rating. Its robust thermoplastic or thermoset housing provides dependable mechanical performance, while the hinged carrier allows straightforward access when inspecting or replacing fuse links.
With a rated current of 32 A, an UL AC voltage rating of 800 V and an UL DC voltage rating of 1000 V, the A1062715 is suitable for protecting motors, transformers, control circuits, drives and low-voltage distribution equipment. Its three-pole configuration enables coordinated protection of three-phase electrical circuits.

Reliable Protection for Industrial Electrical Circuits
Fuse holders provide a secure connection between fuse links and the electrical circuit being protected. When an overcurrent or short circuit occurs, the installed fuse link interrupts the current, helping prevent damage to cables, motors, transformers and connected equipment.
The Mersen Modulostar CUS10 range is engineered for compact industrial control panels where safety, accessibility and efficient use of space are important. The finger-safe construction helps reduce accidental contact with live components, while the DIN rail format simplifies installation alongside other modular protection devices.
