Product Description

Switch Disconnectors

General Characteristics

  • A DC Load Break Switch is normally used as Main and/or Bypass on-load Disconnector in DC systems for:
  • isolating a line for safety or maintenance purpose
  • connecting two adjacent sections of the same line in the event of failure of one or more feeders
  • switching a line from one feeder to the other in case of failure of one of them

ON-LOAD operation guarantees a very high level of service continuity as requested by the modern substations design.

COET LB Load Break switches are available in a large range of current ratings and in single or two pole version, thus allowing to meet different applications.
