When the 3pole breaker is used on a 3phase-4wires system, the
neutral CT (NCT) is required for ground fault protection. As for the
NCT installation, refer to instruction manual (included in the product).

In the case of
✽
low-rating of AE630-SW, G1 module can not be
mounted.
✽
AE630-SW low rating type: 500A, 315A and 250A
Note: If the ground fault current setting Ig is 0.1, it is neces-
sary to control the power supply. (Ground fault pro-
tection does not operate correctly without power
supply.)

Earth leakage current (A)
< Characteristic setting of E1 module >
By combining the ETR with Earth leakage protection(ER) and
External ZCT, earth leakage protection is possible. Control
supply is necessary for this function.
ZCT for load circuit
ZCT with primary conductors
ZCT for ground wire of transformer types
