The motor-charged spring-operated mechanisms type BLK 52 and 152 have been replaced by two new sizes - BLK 82 and 222. BLK 82 and 222 are characterized by an increase of energy stored in the operating mechanism as well as by a reduced 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.
