1) Connection
Connect the control wire to the auxiliary terminal.
For the rear-connected ACB, connect the control wire to the specified terminal on the right side of
the ACB.
For the plug-in ACB, connect the power supply wire to the specified terminal on the rear side of
the mounting base.
2) Contact ratings
Caution : The contact load must fall within the range from the minim load to the rated load.
Caution : The ratings shown on the accessory nameplate are for the resistive/inductive load.
For lamp or motor load, see the following table.
(The lamp load involves an inrush current of 10 times the rated load. The inductive load has a
power factor of 0.4 (AC) and a time constant of 7 ms (DC). The motor load involves an inrush
current of 6 times the rated load.)
