30 years of experience in design and manufacturing of operating mechanisms, with more than 100,000 units delivered to more than 100 different applications has resulted in the new HMC:
- Highest switching reliability by using new design principles such as
- cylinder made from gray cast iron and steel
- new robust valve technology
- wiper protected sealing systems
- gearless pump unit
- integrated close-interlocking with damage-free design
- Lowest life-cycle cost due to
- being maintenance-free for 10,000 CO-operations
- easily accessible and exchangeable modules
- Shortest time-to-market due to
- simple and easy adaptation to all circuit-breaker types
- compatible interface with HMB
- nearly identical travel curve as HMB, allowing alternative operating mechanisms test according to IEC62271-100
