BLK Spring-Operated Mechanisms

Developed for high voltage circuit breakers

The motor-charged spring operated mechanisms BLK 82 and 222 are designed with a minimum number of mechanical components. This ensures a high degree of overall reliability for the circuit breaker and a minimal need for maintenance. Other features are:
  • All power components are carried on one main shaft which by itself is an integral part of the structure.
  • The trip and closing latches are identical, fast acting and vibration proof.
  • A damping device is included to retard the motion of the contact system in the end position.
  • A closed oil-filled worm drive for a minimum of maintenance.
