Operating mechanisms type HMB is the ideal partner for the complete portfolio of high-voltage circuit-breakers.
High degree of acceptance worldwide
- More than 20 different manufacturers with more than 100 switchgear applications trust in HMB operating mechanisms for their high-voltage circuit-breakers. Up to now, more than 110’000 units of HMB and its predecessor have been delivered.
HMB, if “time-to-market” is critical
- Each of the operating mechanisms of the entire HMB family comes as a single unit, combining in a modular design all the functional components. Combination of standard modules with specific modules results in the required variant of the operating mechanism. Prior to the delivery the product is submitted to the most stringent quality and functional testing. Owing to the well devised adaptation program, it takes only a few steps to provide the user with an optimized system of circuit-breaker and operating mechanism.
