Why Choose the Mersen T310011 Fuse Microswitch Accessory?
The Mersen T310011 is a genuine Protistor® fuse microswitch accessory designed for use with Mersen square body semiconductor fuse-links. Identified as the MS3V1-9BS, this accessory provides double-pole, low-level NO/NC indication and is intended for fuse sizes 30 to 33. It enables remote signalling of fuse operation, allowing maintenance personnel and control systems to detect when a protected fuse has operated.
The T310011 mounts alongside compatible Protistor® fuse-links fitted with a striker and converts the mechanical movement of the striker into electrical switching contacts. This makes it suitable for industrial automation, drive systems, power conversion equipment and critical electrical installations requiring remote monitoring of fuse status.
Designed for demanding industrial environments, the Mersen T310011 offers dependable operation and simplifies maintenance by allowing fault indication to be integrated into PLCs, alarms, SCADA systems and other monitoring equipment.

Reliable Remote Fuse Monitoring
When a compatible Protistor® semiconductor fuse operates, its striker mechanically actuates the T310011 microswitch. The change of state can then be monitored by PLCs, alarm circuits, building management systems or industrial control equipment, enabling maintenance personnel to identify fuse operation quickly and minimise equipment downtime.
This accessory is particularly useful in installations where fuse condition cannot easily be inspected visually or where remote fault indication forms part of the equipment's safety or maintenance strategy.
Typical Applications
- Variable speed drives.
- Industrial inverters.
- Power converters.
- UPS systems.
- Motor control centres.
- Industrial automation panels.
- Renewable energy converters.
- Remote alarm and monitoring systems.
