Application
KNL1 series
Residual current circuit breaker (without over-current
protection) is suitable for the line of AC *0/*0Hz, voltage **0V
(2pole)/**5V (4pole), rated current up to **0A. When there is
human electricity shock or if the leakage current of the line
exceeds the prescribed value, it will cut off the power rapidly
to protect human safety and prevent the accident due to the
current leakage. It can be used as infrequent changeover of the
line in normal situation. It is applicable to industrial site,
commercial site, tall building and civil house.
It complies with standard of IEC/EN****8.1 and
GB****6.1.

Operation
principle
Each phase of
conductor at the circuit breaker passes through the zero-sequence
current transformer, and the secondary side of coil connects with
the electromagnetic tripper. Under normal condition, the vector
sum of each phase of current passing through zero-sequence
current transformer is zero. The flux of the zero-sequence
current transformer is zero. And the secondary output voltage is
zero and the circuit breaker doesn’t zero, and the
zero-sequence current transformer would produce the magnetic
flux, and the secondary side of coil would output the voltage.
Once the leak current increases to drive the output voltage at
the secondary side to grow to certain level, the electromagnetic
release would activate to drive the operation mechanism to act to
break the contact that connects the power, finally to realize the
leak protection.
