Why Choose the Mersen W1062711 CUS103N Modulostar® Fuse Holder?
The Mersen W1062711, also identified by catalogue reference CUS103N, is a robust 3-pole plus neutral cylindrical fuse holder designed for reliable overcurrent protection and coordinated circuit isolation in industrial control panels, machinery and electrical distribution systems. As part of the Mersen Modulostar® CUS10 series, it is suitable for 10 × 38 mm Midget fuse links.
The CUS103N is rated for fuse currents up to 32 A and supports demanding AC and DC applications, with UL voltage ratings of up to 800 V AC and 1000 V DC. Its three fused poles and associated neutral pole provide a practical solution for three-phase systems requiring simultaneous phase and neutral isolation.
Featuring an IP20 finger-safe design, the W1062711 helps reduce the risk of accidental contact with live components, including during fuse replacement. Its compact modular construction, durable housing and standard DIN rail mounting make it ideal for panel builders, OEM manufacturers and industrial maintenance teams.

Reliable Three-Phase Protection with Neutral Isolation
The Mersen W1062711 provides secure mounting and connection for three 10 × 38 mm Midget fuse links while incorporating a dedicated neutral pole within the same modular assembly. When an overload or short circuit occurs, the fitted fuses interrupt the affected phase circuits according to their operating characteristics.
The associated neutral pole enables coordinated isolation during installation, testing and maintenance. Combined with finger-safe construction and a compact DIN rail format, the CUS103N helps panel builders create organised, accessible and dependable protection systems for industrial AC and DC equipment.
