Switch Disconnectors

Switch Disconnectors provide the means to safely disconnect an item of electrical equipment from the supply. Primarily designed to provide a means of local isolation when an elecrical item may need maintenance or repair, a Switch Disconnector has to comply with the following minimum requirements:-

  • Provide an effective clearance between the supply and the load appropriate to the voltage applied.
  • Provide a means of locking in the 'Off' position. (Padlocking)
  • Provide a true indication of the contact state.
  • Provide a safe disconnection from the supply even under fault conditions.

All of Craig & Derricott's Switch disconnectors meet, and often exceed, the above requirements making each, the product of choice in today's market.
