Maintanance-free DC contactor DILDC

Thanks to the use of proven hybrid technology, the contacts in Eaton DC contactors have a long lifespan and low contact wear:

Hybrid contactors feature two mechanical contacts- a extinguishing ocntact and a break contact -that are connnected in series.Moreover, they have IGBT power semiconductor switch connected in parallel with extinguishing contact. When one of these contactors is switched off, the first thing that happens is that the IGBT is switched on. After this, the extinguishing contact opens mechanically, commutating the current to the IGBT so that it can be interrupted by the power electronics. Finally, the break contact is opened in a de-genergized state, achieveing the required potential isolation.

Together with this configuration, a wide-range coil for DC & AC voltage makes our DC contactors a maintenance-free and reliable part of any machine system.
