Emergency Disconnect Switch

The EVI200 system is supplied with main contactors. It's unclear if any additional equipment is required for emergency disconnection. Anderson disconnects or circuit breakers should be used when performing maintenance.

  • Gigavac GX12 - a contactor that can almost do the job from the specs (gigavac have said that it will do the job via email).
  • EV200] - (Gigavac and Kilovac comparison [here) - includes optional aux contacts
  • LEV200 - a contactor that will do the job according to specs (available here, rs pricing here.). This contactor doesn't have auxiliary contacts, making it complicated to verify if it is working.
