The COB901 is a semiconductor integrated circuit
with amplifier for a high-speed earth leakage circuit
breaker. The COB901,an advanced ground fault in-
terrupter consists of differential amplifier, internal time
delay,latch circuit and precision voltage reference.
It is connected to the secondary side of the zero
current transformer(ZCT) which detects leakage
current in the both inputs of the differential amplifier. It
drives a thyristor connected to the output terminal of
latch circuit. The internally integrated high frequency
noise filter can eliminate the abnormal input noises.
The operational amplifier
’s output noise rejection and
adequate time delay acquirements that are specified
in KSC4613 can be achieved by internal blanking
circuit.
