N-phase external transformer:
In the 3P + n grounding mode, the external transformer used to measure the
neutral phase current is sheathed on the wiring busbar by the user
One out of three with grounding transformer and leakage transformer
Grounding transformer:
The special external transformer used to measure the neutral phase current can
protect the upper and lower grounding faults of the circuit breaker at the same
time
The grounding mode is current return type
iTR326H ETU only
One of three options: outward connected transformer and leakage transformer
with N
Leakage transformer:
When the grounding protection is leakage type, a special rectangular
transformer is added
iTR326H ETU only
One of three options: outward connected transformer and leakage transformer
with N
Power converter:
It can provide auxiliary power for intelligent controller in AC220V / AC230V /
AC380V / AC400V / DC110V / DC220V circuit
Input: AC220V / AC230V / AC380V / AC400V / DC110V / DC220V, input
fluctuation range ± 20%
Output is DC24V, output fluctuation range ± 5%
Output 3 sets of DC24V: total power 7W
Before power on test of each switch, check whether it is connected to the power
module to avoid damage to the intelligent controller after power on
Signal conversion module:
The output signal unit is used for communication functions, such as regional
interlocking, signal processing of four remote functions, or fault alarm or
indication, etc
iTR326H ETU only
