The ABB OMD800E480C is an automatic transfer switch controller designed to manage the automatic switching of electrical loads between two independent power sources (such as utility mains and a standby generator) in low‑voltage three‑phase systems. It serves as the intelligence and logic module for an automatic transfer switch (ATS), working with ABB motorized change‑over switches to perform safe and reliable source transfers.
