Exel 2 Fuse Switch-Disconnectors

Exel 2 switch disconnectors and switch-disconnector fuses 

• Units have removable moving contact assemblies to facilitate wiring. 
• Exel 2 surface-mounting enclosures are fabricated from rust-protected sheet steel with a light grey paint finish.
• Removable blank top and bottom end plates (except for 20 and 32A top end plates which incorporate knockouts) and gasket doors give IP41 protection.
• Chromium-plated front operated handles, with “ON (I) OFF (O)” indication, and internal fixing enabling units to be mounted closely side by side.
• Interiors comprise porcelain bases fitted with non-ferrous conducting components.

Fuses and fuse carriers

• HRC fuse carriers are designed for offset contact fuse links to BS 88: Part 2. 
• Eaton HRC fuse links fitted to switch-disconnector- fuses are suitable on systems up to 415V AC. 
• Eaton fuses used in these products are also suitable for 250V DC systems. 
• All performance tests have been carried out using Eaton BS88 fuselinks. 
• Units are fitted with HRC Fuselinks of maximum rating but will accept fuselinks of a lower rating 
• HRC pattern switchfuses are fitted with type SCH carriers (20A, 32A, 63A-moulded; 100A, 125A-porcelain).

Motor ratings

• The motor ratings assigned to TPN switch-disconnector units are utilisation category AC23A (frequent operation) to BS EN 60947-3, which calls for make and break testing at 10 and 8 times rated current respectively for units having a motor rating up to and including 100 Amps. 
• Ratings for switch-disconnector-fuses are dependent on suitable HRC fuses being fitted.

Cable size

Maximum cable sizes are: 20A–6mm2, 32A–10mm2, 63A–35mm2, 100/125A–70mm2.
