The Mersen TSF1250-13 is a dedicated terminal shroud for compatible 1250 A UL 98 fusible disconnect switches. Designed to cover exposed electrical terminals, it creates an insulating barrier that helps reduce the risk of accidental contact with live connections inside industrial switchboards, distribution panels and control enclosures.
Manufactured specifically for Mersen fused disconnect switch assemblies, the TSF1250-13 provides dependable compatibility with the associated switch design. Its durable polycarbonate construction offers effective electrical insulation while supporting a neat, secure and professionally finished installation.
The Mersen TSF1250-13 terminal cover is intended for the line-side terminals of compatible 1250 A, 600 V AC, single-pole fusible disconnect switch configurations. It is particularly suitable for high-current power isolation systems where additional protection around switch terminals is required.

Reliable Protection for High-Current Switch Terminals
Fusible disconnect switches provide both circuit isolation and fuse-based overcurrent protection within industrial electrical systems. Where high-current terminals are present, purpose-designed terminal shrouds help improve safety by creating a physical insulating barrier around the electrical connection points.
The Mersen TSF1250-13 is engineered for compatible 1250 A fusible switch installations. Its manufacturer-specific design ensures that the shroud fits correctly around the associated line-side terminal while retaining practical access for wiring, inspection and maintenance.
Typical Applications
Industrial power distribution switchboards.
High-current fused isolation systems.
Motor control centres.
Manufacturing and process control equipment.
Commercial and industrial electrical panels.
OEM machinery and power distribution enclosures.
