Why Choose the Mersen CMC103NR Modulostar Fuse Holder?
The Mersen CMC103NR, manufacturer item number C1062694, is a compact three-pole plus switched-neutral modular fuse holder designed for 10 × 38 mm cylindrical fuse links. Part of the Mersen Modulostar CMC10 series, it provides reliable circuit protection and coordinated isolation for three-phase electrical systems that include a neutral conductor.
Rated at 32 A and up to 690 V AC, the CMC103NR is suitable for industrial control panels, machinery, low-voltage distribution systems and automation equipment. Its switched-neutral configuration allows the three phase conductors and neutral conductor to be operated together, supporting safe and orderly circuit isolation.
The fuse holder features an IP20 finger-safe design under applicable IEC requirements, including during normal fuse replacement. Its compact four-module construction mounts directly onto a standard 35 mm DIN rail and can be locked to support controlled maintenance and isolation procedures.
Key Advantages
- Three-pole plus switched-neutral fuse holder for three-phase systems.
- Compatible with 10 × 38 mm cylindrical fuse links.
- 32 A current rating for industrial circuit protection.
- Rated for operation at up to 690 V AC.
- IP20 finger-safe construction under applicable IEC requirements.
- Simultaneous operation of the three phase poles and neutral conductor.
- Lockable design supports controlled isolation and maintenance.
- Compact mounting on a standard 35 mm DIN rail.

Coordinated Protection for Three-Phase and Neutral Circuits
The CMC103NR provides secure mounting for three cylindrical fuse links while incorporating a switched neutral pole. This allows the phase conductors and neutral conductor to be isolated together, making the device suitable for three-phase, four-wire electrical systems.
The Modulostar construction combines durable insulating materials with finger-safe operation and compact DIN rail mounting. The holder is intended for off-load switching and should only be opened or closed when the connected circuit has been safely de-energised.
Typical Applications
- Three-phase industrial control panels.
- Machinery and automation equipment.
- Motor and drive protection circuits.
- Low-voltage distribution systems.
- Transformer and power supply protection.
- Commercial electrical switchboards.
- OEM panel-building projects.
