T093903

Overview

The Mersen T093903 is a high-speed cylindrical fuse insert belonging to the 6.900 CP URC series, designed for demanding industrial applications. It features a 14x51 mm physical dimension and operates at a rated voltage of 12V DC. The component provides reliable circuit protection with a breaking capacity suitable for high-speed interruption requirements.

Feature Summary

• High-speed interruption capability for sensitive electronic circuits
• Cylindrical ceramic body construction for durability
• URC series designation indicating specific performance characteristics

Applications

• Industrial power distribution systems
• High-speed fuse gear assemblies
• DC circuit protection equipment

Procurement Notes

Verify the exact voltage rating (12V) and current specifications against the official Mersen datasheet before integration. Confirm that the 14x51 mm form factor matches the existing holder dimensions. Ensure the application environment supports the thermal and electrical limits defined in the manufacturer's documentation.

Selection Notes

Select this component when high-speed fusing is required within a 14x51 mm cylindrical housing. Compare the 6.900 CP URC series specifications against alternative Mersen fuse inserts to ensure compatibility with the system's voltage and current requirements. Validate the breaking capacity against potential fault currents.

Part Context

This part is part of the Mersen 6.900 CP URC family of high-speed fuses. These components are engineered for rapid response in protecting semiconductor devices and other sensitive loads from overcurrent conditions. The series is widely used in industrial automation and power electronics.

Replacement Considerations

Direct substitutes include Mersen part numbers V093904 (14.51/16) and W093905 (20A), which share the same 14x51 mm form factor and series characteristics but differ in current ratings.
