This is for the mid-circuit-interrupter made by Tesla. For Delta’s MCI, go to MCI (Middle Circuit Interrupter).

MCI-1 works like module-level rapid shutdown, but interrupts the circuit mid-string, instead. With UL 3741, it can be used to interrupt strings before they exit the array. Only compatible with Tesla equipment at this time.

Tesla does not advertise details about their equipment on their website, so make sure you have the most up-to-date documents from your manufacturer/supplier before using this equipment.

You may notice that the datasheet mentions Tesla/Zep ZS Arrays as well. Tesla does not sell this racking publicly and thus will not be included on this website.
