˜ To provide ground fault protection for a 3-pole breaker used in the 3-phase 4-wire system, a neutral pole CT (NCT) is required. For the specification, refer to the catalog.

For the installation of the NCT, refer to the instruction manual provided with the NCT.

˜ The G1 module cannot be attached to the AE630-SW low rating models (CT rating:

500 A, 315 A, 250 A).

To set the ground fault pick-up current Ig to 0.1, the control power supply must be applied. (If the control power supply is not applied, ground fault protection cannot be provided correctly.)

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.

< N5 module >

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.
