Disconnect Switch Type Combination Starters

Switch-type combination starters are available with fusible or non-fusible disconnect switches. Switches are constructed of a molded, insulated material that delivers arc-quenching performance similar to that of high voltage switch-gear. Visible blade construction confirms safety and proper performance at a glance. Many industries have standardized on this feature.
Non-fusible assemblies can be field converted to fusible designs easily and quickly. Factory-built, fusible units will accept the industry standard Class H, K or J fuses. Class R fuse clip kits can be factory or field installed to meet rejection fuse requirements.

The various units have specific, UL listed short circuit withstand ratings that range from 5,000 to 100,000 amperes. Specific ratings are influenced by many components, including the size of the disconnect switch and the type of fuses used with the switch.
