HySecurity MX000844 is a 24 VDC, 180 amp disconnect switch used in compatible HySecurity DC power supply systems. HySecurity power supply parts references identify MX000844 as the DC power supply disconnect switch used in UPS-style systems. This part is used to isolate the DC side of the power supply or battery system during service and to maintain the correct factory power-control arrangement. Because it is a high-current DC component, it must be matched exactly by voltage, current rating, terminal layout, mounting style, and wiring diagram. A damaged disconnect switch may show heat discoloration, loose terminals, high resistance, intermittent power loss, or failure to isolate power correctly.
