Current transformer for neutral line (separate type)
When using a 3-pole ACB with the ground fault protection function to protect a 3-phase, 4-wire system against ground fault, install
an appropriate current transformer (CT) to the neutral line of the system.
TERASAKI can provide this neutral line CT as an option.
For the 4-pole ACB, a measuring CT instead of the neutral line CT is already built into the neutral phase of the ACB when the
ground fault protection is fitted.

Contact Terasaki for how to check the reverse power trip function.
The over-current trip device of
TemPower2
provides a ground fault protection on the line side (optional) as well as on the load side
as shown above. When the ACB is used for protection of a 3-pole, 4-wire system, select the same current transformer for the neutral
line shown above.
