Medium Voltage Circuit Breaker Switching Pole

A medium voltage circuit breaker switching pole, comprising:

• a fixed contact of a vacuum interrupter;
• a movable contact of the vacuum interrupter;
• and
• a threaded drive element,
• wherein:
• the movable contact is configured to move along a longitudinal axis of the vacuum interrupter,
• a centre axis of the threaded drive element is parallel to the longitudinal axis of the vacuum interrupter,
• when in an open configuration the fixed contact and the movable contact are separated from one another,
• when in a closed configuration the fixed contact and the movable contact are in contact with one another,
• rotation of the threaded drive element about the centre axis of the threaded drive element in a first direction is configured to transition the switching pole from the open configuration to the closed configuration, and
• rotation of the threaded drive element about the centre axis in a second direction counter to the first direction is configured to transition the switching pole from the closed configuration to the open configuration.
