Why Choose the Mersen CMS223M2 Modulostar Fuse Holder?
The Mersen CMS223M2, item number C331087, is a three-pole IEC cylindrical fuse holder designed for reliable overcurrent protection and remote fuse-status monitoring in industrial electrical systems. Part of the Mersen Modulostar CMS22 series, it accepts 22 × 58 mm cylindrical fuse-links and is suitable for demanding control-panel, machinery and power-distribution applications.
Rated for currents up to 125 A and operating voltages up to 690 V AC or 690 V DC, the CMS223M2 provides a robust solution for protecting three-phase electrical circuits. Its three mechanically linked poles allow the fuse-links to be isolated together, supporting safer maintenance and straightforward system operation.
This version incorporates two microswitches for remote signalling and monitoring. These auxiliary contacts can be integrated into control, alarm or building-management systems to indicate the operating status of the fuse holder. The finger-safe IP20 construction helps prevent accidental contact with live components, including during fuse replacement.

Reliable Protection with Remote Fuse Monitoring
When fitted with correctly selected 22 × 58 mm fuse-links, the Mersen CMS223M2 protects cables, motors, drives, transformers and other electrical equipment against damaging overload and short-circuit currents. Its three-pole design makes it particularly suitable for coordinated protection of three-phase electrical supplies.
The two integrated microswitches allow the fuse holder’s status to be communicated to external control equipment. This can help maintenance personnel identify circuit interruptions quickly, reduce fault-finding time and improve the operational visibility of critical industrial installations.
Typical Applications
- Three-phase industrial distribution systems.
- Motor and transformer protection circuits.
- Variable speed drive control panels.
- Industrial machinery and production equipment.
- Automation and process-control cabinets.
- Low-voltage switchboards.
- Heating and ventilation equipment.
- OEM machinery and panel-building projects.
