Where do I find a description for the MSD operating mechanism?

Joop Feikes-de-Groot, Global Product Marketing Manager Cooling Systems

ABB's answer

The MSD spring operating mechanism is designed with a minimum of components. Such a design ensures a high degree of total reliability and minimal need for maintenance for the operating mechanism and, thus, the circuit breaker as a whole.
