By combining this with the pre-alarm function installed as
standard, the two-step pre-alarms can be constructed.
For the AE630-SW low rating types, be sure to apply the
control power supply.
This cannot be combined with the WB type.

LTD and pre-alarm characteristics of the neutral pole are 50% of the voltage pole.
However, STD and INST characteristics are the same as for the voltage pole (100%).
For the AE630-SW low rating types, be sure to apply the control power supply.
This cannot be combined with the WB type.
