CT ratio range
150:5 to 10,000:5
Note
If there are certain requirements concerning the cable temperature,
the specification of the cable must be enhanced
Note:
1. If the current of the fundamental is the main part of the total current (fundamental and
harmonic), the wire cross section of the N-conductor should be 3 times larger than the
phase conductor cross section.
2. The CT ratio should be selected to be 1.5 to 4 times that of the maximum
load current.
3. The rated current of the circuit breaker should be selected to be 1.2 times
the rated capacity of the AHF, or more.
