Why Choose the Mersen CMS22W3 Auxiliary Switch Accessory?
The Mersen CMS22W3, manufacturer item number N331189, is an auxiliary switch accessory designed for compatible Mersen Modulostar® CMS22 modular fuse holders. It enables electrical fuse-holder status to be transmitted to an external monitoring, signalling or control circuit.
Developed for use with CMS22 fuse holders accepting 22×58 mm cylindrical fuse links, the CMS22W3 provides a practical way to integrate fuse monitoring into industrial automation systems. The accessory can support remote fault indication through PLCs, alarm circuits, indicator devices or supervisory control equipment.
The CMS22W3 is intended for compatible three-pole CMS22 assemblies, helping panel builders add remote status monitoring without replacing the complete fuse-holder arrangement. Its purpose-designed construction supports reliable operation in industrial control panels, switchboards, machinery and electrical distribution equipment.

Remote Fuse Status Monitoring for Industrial Systems
The Mersen CMS22W3 enables a compatible CMS22 fuse-holder assembly to communicate status information to an external electrical circuit. This allows an operated fuse or change in fuse-holder state to trigger an alarm, indicator or input signal within an industrial control system.
Remote indication is particularly valuable where fuse holders are installed inside enclosed panels, distributed switchboards or machinery that cannot be inspected continuously. By integrating the CMS22W3 with a suitable monitoring system, maintenance teams can locate affected circuits more efficiently and respond quickly to electrical faults.
Typical Applications
- Industrial control panels.
- Electrical switchboards.
- Motor control centres.
- OEM machinery and production equipment.
- PLC-monitored fuse circuits.
- Alarm and fault-signalling systems.
- Industrial power distribution equipment.
