Mechanical interlocks

Application:

Intended for organizing mechanical operational interlocking between a high-voltage circuit breaker and a disconnector.
  • In 7.2-12 kV KSO cubicles of the 2nd and 3rd series
  • When retrofitting old 26x, 27x series KSO cubicles

Operating principle:

A spring-loaded rod with threaded (M10) ends moves in a vertical direction. The rod position is fixed by a spring-loaded catch. Rod stroke is 22 mm. To unlock the rod, it is necessary to pull the catch towards oneself. The interlock is additionally equipped with a position limit switch. The limit switch is 3-contact: NO+NC with a common end. Switch parameters: 2A, AC 220V.
