FXM250 is a complete manual source changeover assembly for two Compact INS250 3 poles switch disconnectors. It provides an easy way to implement source changeover functions with small size,taking up less room in the switchboard. The operational current is 250A at 690VAC 50/60Hz,in categories AC22A/AC23A. The operational current is 250A at 125VDC (2 poles in series) or at 250VDC (4 poles in series),in categories DC22A/DC23A. There is a single 3 position rotary handle that controls the two switch disconnectors (normal source ON,OFF,replacement source ON). A complete source changeover assembly can be ordered with a single catalogue number. A complete source changeover assembly can be ordered with a single catalogue number.
