Elevator phase sequence protection relay XJ3-G AC380V 1 open 1 closed

Note:
XJ3-2 phase failure protection (protection function is only useful at startup)
XJ3-5 three-phase unbalance protection: 5.5%~7%; if any one of the three phases is missing, the action time is ≤3s
XJ3-G three-phase unbalance protection: 5.5%~7%; if any of the three phases is missing, the action time is ≤3s
The XJ3-D protection function is that the overvoltage protection voltage is adjustable from AC380V to AC460V, and the action time is adjustable from 1.5s to 4s; the undervoltage protection voltage is adjustable from AC300V to AC380V, and the action time is adjustable from 2s to 9s.
XJ9 protection function is overvoltage protection voltage AC380V~AC460V adjustable; undervoltage protection voltage AC300V~AC380V adjustable, action time adjustable from 2s~8s, no specification code (2, 5, G, D)
