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.
