down. Therefore, for medical IT systems composed of medical isolation transformers and insulation
monitoring products, in the selection of inlet circuit breaker of the isolation transformer, it
is recommended to choose the circuit breakers only with short circuit protection but without overload
protection according to GB requirements. If choosing the circuit breaker with overload protection,
the circuit breaker should conform to the C and D tripping curves of GB14048.2-2008, and the rated
current of the circuit breaker should be determined according to the capacity of the isolation
transformer as follows: 10kVA-63A, 8kVA-50A, 6.3kVA-40A, 5kVA-40A, 3.15kVA-20A.
If the circuit breaker selection is not in accordance with the above requirements, the company shall
not be liable for any medical malpractice caused by the closure difficulty of the circuit breaker
or the disconnection of the circuit breaker during operation.

When the insulation resistance exceeds the alarm value, or when the LL/FK
is disconnected, the indicator light flashes to alarm.
Overload
When load current exceeds the total load current of transformer, the
indicator light flashes to alarm.
