Mersen TS40-1 single-pole terminal shroud for compatible 40 A UL 508 non-fused disconnect switches, providing an insulating cover over an exposed line-side or load-side terminal.
£4.40
The Mersen TS40-1 is a genuine single-pole terminal shroud designed for compatible Mersen 40 A UL 508 non-fused disconnect switches. It provides an electrically insulating cover over an exposed switch terminal, helping reduce the risk of accidental contact with live conductive parts inside industrial control panels, machinery enclosures and electrical distribution equipment.
Manufactured as a dedicated Mersen switch accessory, the TS40-1 offers dependable fitment with compatible switch-disconnector assemblies. Its compact construction protects the selected terminal while supporting the space-efficient panel layouts commonly required by machine builders and industrial automation engineers.
The TS40-1 is supplied as a one-pole terminal shroud and is compatible with selected Mersen 4P40 and NP40 switch accessories. It may be installed over a compatible terminal on either the line or load side, subject to the configuration and installation instructions of the selected disconnect switch.
Disconnect-switch terminals may remain accessible after electrical conductors have been installed. A terminal shroud adds a physical insulating barrier over the connection point, helping improve personnel protection during panel assembly, inspection and maintenance.
The Mersen TS40-1 protects one terminal position on a compatible switch assembly. The correct mounting location and number of shrouds required should be confirmed against the precise switch configuration and applicable Mersen installation documentation.
